Item 2. Identity and Background This statement is being filed by Mario J. Gabelli ("Mario Gabelli"), Marc J. Gabelli ("Marc Gabelli") and various entities which either one directly or indirectly controls or for which either one acts as chief investment officer. These entities, except for Lynch Corporation ("Lynch"), Spinnaker Industries, Incorporated ("Spinnaker"), Western New Mexico Telephone Company ("Western New Mexico"), Entoleter, Inc. ("Entoleter"), Lynch Telecommunications Corporation ("Lynch Telecom"), Lynch Telephone Corporation ("Lynch Telephone") and Inter-Community Telephone Company ("Inter-Community") (collectively, "Lynch and its affiliates"), engage in various aspects of the securities business, primarily as investment adviser to various institutional and individual clients, includ- ing registered investment companies and pension plans, as broker/dealer and as general partner of various private invest- ment partnerships. Certain of these entities may also make investments for their own accounts. The foregoing persons in the aggregate often own beneficially more than 5% of a class of equity securities of a particular issuer. Although several of the foregoing persons are treated as institutional investors for purposes of reporting their beneficial ownership on the short-form Schedule 13G, the holdings of those who do not qualify as institutional investors may exceed the 1% threshold presented for filing on Schedule 13G or implementation of their investment philosophy may from time to time require action which could be viewed as not completely passive. In order to avoid any question as to whether their beneficial ownership is being reported on the proper form and in order to provide greater investment flexibility and administra- tive uniformity, these persons have decided to file their benefi- cial ownership reports on the more detailed Schedule 13D form rather than on the short-form Schedule 13G and thereby to provide more expansive disclosure than may be necessary.

(d) and (e) - On December 8, 1994, the SEC instituted and simultaneously accepted offers for the settlement of an administrative proceeding against Gabelli & Company and GAMCO. The order instituting the proceeding included a finding, which Gabelli & Company and GAMCO neither admitted nor denied, that they failed to implement and maintain policies and procedures reasonably designed to prevent the misuse of material, nonpublic information by not specifically addressing the special circumstances that arose from their affiliation with Lynch Corporation, a public company. To resolve this matter, Gabelli & Company and GAMCO agreed to cease and desist from violating Section 15(f) of the 1934 Act and Section 204A of the Advisers Act, respectively. They further agreed to each pay a civil penalty in the amount of $50,000, and to retain, and adopt the recommendations of, an independant consultant regarding their Section 15(f) and Section 204A policies and procedures. (f) - Reference is made to Schedule I hereto. Item 3. Source and Amount of Funds or Other Consideration All Reporting Persons used an aggregate of approximate- ly $4,544,495 to purchase the Securities reported as beneficially owned in Item 5 below. GAMCO, Gabelli Funds, Gabelli Advisers used approximately $833,755, $978,750 and $262,000, respectively, of funds that were provided through the accounts of certain of their investment advisory clients (and, in the case of some of such accounts at GAMCO, may be through borrowings from client margin accounts) in order to purchase the Securities for such clients. Gabelli Associates used approximately $1,287,000 of the investing funds of the Partnership to purchase the Securities reported by it. GAL, GIL and LDC used approximately $583,650, $130,800 and $39,330, respectively of working capital to purchase the Securities reported by them. MJG Associates used approximately $38,310 of client funds to purchase the Securities reported by it. The Foundation used approximately $390,900 of funds from the Foundation's assets to purchase the Securities reported by it. Item 4. Purpose of Transaction Each of the Reporting Persons, with the exceptions of Lynch and its affiliates, has purchased and holds the Securities reported by it for investment for one or more accounts over which it has shared, sole, or both investment and/or voting power, for its own account, or both. The Reporting Persons, with the exceptions of Lynch and its affiliates, are engaged in the business of securities analysis and investment and pursue an investment philosophy of identifying undervalued situations. In pursuing this investment philosophy, the Reporting Persons analyze the operations, capital structure and markets of companies in which they invest, including the Issuer, on a continuous basis through analysis of documentation and discussions with knowledgeable industry and market observers and with representatives of such companies (often at the invitation of management). The Reporting Persons do not believe they possess material inside information concerning the Issuer. As a result of these analytical activities one or more of the Reporting Persons may issue analysts reports, participate in interviews or hold discussions with third parties or with management in which the Reporting Person may suggest or take a position with respect to potential changes in the opera- tions, management or capital structure of such companies as a means of enhancing shareholder values. Such suggestions or positions may relate to one or more of the transactions specified in clauses (a) through (j) of Item 4 of the Schedule 13D form, including, without limitation, such matters as disposing of one or more businesses, selling the company or acquiring another company or business, changing operating or marketing strategies, adopting or not adopting, certain types of anti-takeover measures and restructuring the company's capitalization or dividend poli- cy. Each of the Reporting Persons intends to adhere to the foregoing investment philosophy with respect to the Issuer. How- ever, none of the Reporting Persons intends to seek control of the Issuer or participate in the management of the Issuer, and any Reporting Person that is registered as an investment company under the l940 Act will participate in such a transaction only following receipt of an exemption from the SEC under Rule l7D-l under the l940 Act, if required, and in accordance with other applicable law. In pursuing this investment philosophy, each Reporting Person will continuously assess the Issuer's business, financial condition, results of operations and prospects, general economic conditions, the securities markets in general and those for the Issuer's securities in particular, other developments and other investment opportunities, as well as the investment objectives and diversification requirements of its shareholders or clients and its fiduciary duties to such shareholders or clients. Depending on such assessments, one or more of the Reporting Persons may acquire additional Securities or may determine to sell or otherwise dispose of all or some of its holdings of Securities. Although the Reporting Persons share the same basic investment philosophy and although portfolio decisions are made by or under the supervision of Mario Gabelli, the investment objectives and diversification requirements of various clients differ from those of other clients so that one or more Reporting Persons may be acquiring Securities while others are disposing of Securities. With respect to voting of the Securities, the Reporting Persons have adopted general voting policies relating to voting on specified issues affecting corporate governance and sharehold- er values. Under these policies, the Reporting Persons generally vote all securities over which they have voting power in favor of cumulative voting, financially reasonable golden parachutes, one share one vote, management cash incentives and pre-emptive rights and against greenmail, poison pills, supermajority voting, blank check preferred stock and super-dilutive stock options. Exceptions may be made when management otherwise demonstrates superior sensitivity to the needs of shareholders. In the event that the aggregate voting position of all joint filers shall exceed 25% of the total voting position of the issuer then the proxy voting committees of each of the Funds shall vote their Fund's shares independently. Each of the Covered Persons who is not a Reporting Person has purchased the Securities reported herein as benefi- cially owned by him for investment for his own account or that of one or more members of his immediate family. Each such person may acquire additional Securities or dispose of some or all of the Securities reported herein with respect to him. Other than as described above or in Item 4(c) below, none of the Reporting Persons and none of the Covered Persons who is not a Reporting Person has any present plans or proposals which relate to or would result in any transaction, change or event specified in clauses (a) through (j) of Item 4 of the Schedule 13D. Item 5. Interest In Securities Of The Issuer (a) The aggregate number and percentage of Securities to which this Schedule 13D relates is 349,500 shares, repre- senting 6.70% of the 5,219,800 shares outstanding as reported in the Issuer's most recently filed Form 10-Q for the quarter ended September 26, 1998. The Reporting Persons beneficially own those Securities as follows: Shares of % of Common Class of Name Stock Common Gabelli Funds: As Principal 0 0.00% As Agent 75,000 1.44% GAMCO: As Principal 0 0.00% As Agent 63,500 1.22% Gabelli Associates 100,000 1.92% GAL 45,000 0.86% GIL 10,000 0.19% LDC 3,000 0.06% MJG Associates 3,000 0.06% Foundation 30,000 0.57% Marc Gabelli 0 0.00% Mario Gabelli 0 0.00% Mario Gabelli is deemed to have beneficial ownership of the Securities owned beneficially by each of the foregoing persons other than Marc Gabelli. MJG Associates is deemed to have beneficial ownership of the Securities beneficially owned by GIL and LDC. GAMI and GFI are deemed to have beneficial ownership of the Securities owned beneficially by each of the foregoing persons other than Mario Gabelli, Marc Gabelli and the Foundation. (b) Each of the Reporting Persons and Covered Persons has the sole power to vote or direct the vote and sole power to dispose or to direct the disposition of the Securities reported for it, either for its own benefit or for the benefit of its investment clients or its partners, as the case may be, except that (i) Gabelli Funds has sole dispositive and voting power with respect to the shares of the Issuer held by the Funds so long as the aggregate voting interest of all joint filers does not exceed 25% of their total voting interest in the Issuer and, in that event, the Proxy Voting Committee of each Fund shall respectively vote that Fund's shares, (ii) at any time, the Proxy Voting Committee of each such Fund may take and exercise in its sole discretion the entire voting power with respect to the shares held by such fund under special circum- stances such as regulatory considerations, and (iii) the power of Mario Gabelli, Marc Gabelli, GAMI and GFI is indirect with respect to Securities beneficially owned directly by other Reporting Persons. (c) Information with respect to all transactions in the Securities which were effected during the past sixty days or since the most recent filing on Schedule 13D, whichever is less, by each of the Reporting Persons and Covered Persons is set forth on Schedule II annexed hereto and incorporated herein by refer- ence. (d) The investment advisory clients of Gabelli Funds, Gabelli Advisers, GAMCO, MJG Associates and Gemini, the partners of the various partnerships managed by Mario Gabelli and GSI (including GPP, Gabelli Associates, ALCE, and Multimedia Partners to the extent of their economic interest there-in) and the shareholders of GIL, GIL II and LDC which Mario Gabelli manages and GAL which is managed by GSI have the sole right to receive and, subject to the notice, withdrawal and/or termination provi- sions of such advisory contracts and partnership arrangements, the sole power to direct the receipt of dividends from, and the proceeds of sale of, any of the Securities beneficially owned by such Reporting Persons. Except as noted, no such client or partner has an interest by virtue of such relationship that relates to more than 5% of the Securities. (e) Not applicable. Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer The powers of disposition and voting of Gabelli Funds, Gabelli Advisers, GAMCO, MJG Associates and Gemini with respect to Securities owned beneficially by them on behalf of their investment advisory clients, of Mario Gabelli and GSI with respect to Securities owned beneficially by them on behalf of the partnerships which they directly or indirectly manage, and of GIL, GIL II, GAL, LDC and GIGFL with respect to Securities owned beneficially by them on behalf of their shareholders, are held pursuant to written agreements with such clients and partnerships.
