Item 1. Security and Issuer

This statement relates to shares of Common Stock (the "Stock") of Sparton Corporation (the "Issuer"). The principal executive office of the Issuer is located at 2400 E. Ganson St., Jackson, MI 49202.

Item 2. Identity and Background

The persons filing this statement and the persons enumerated in Instruction C of Schedule 13D and, where applicable, their respective places of organization, general partners, directors, executive officers and controlling persons, and the information regarding them, are as follows:

(a) Lawndale Capital Management, LLC, a California limited liability company ("LCM"),
Diamond A. Partners, L.P., a California limited liability company ("DAP")
and
Andrew E. Shapiro ("Shapiro")
(collectively, the "Filers").

LCM and Shapiro disclaim beneficial ownership of the Stock except to the extent of their respective pecuniary interests therein. DAP is filing jointly with the other filers, but not as a member of a group, and expressly disclaims membership in a group. In addition, the filing of this Schedule 13 on behalf of DAP should not be construed as an admission that it is, and it disclaims that it is, the beneficial owner of any of the Stock covered by this Statement.

(b) The business address of the Filers is
One Sansome Street, Suite 3900, San Francisco, CA 94104.

(c) Present principal occupation or employment or the Filers and the name, principal business and address of any corporation or other organization in which such employment is conducted:
LCM is an investment adviser. Shapiro is the sole manager of LCM.

(d) During the last five years, none of the Filers has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors).

(e) During the last five years, none of the Filers was a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

(f) Shapiro is a citizen of the United States of America.

Item 3. Source and Amount of Funds or Other Consideration

The source and amount of funds used in purchasing the Stock were as follows:

Purchaser	Source of Funds	Amount

Shapiro	PF	$7,872.50
DAP	WC	$3,090,158.74

(1) Includes funds of DAP

Item 4. Purpose of Transaction

The Filers ("Lawndale") have been and may continue to be in contact with Sparton Corp. ("Sparton") management, members of Sparton's Board of Directors, other significant shareholders and others regarding alternatives that Sparton could employ to maximize shareholder value, including, but not limited to, value-added and accretive deployment of Sparton's substantial excess cash. Lawndale has also had discussions with these parties regarding the composition, independence and functioning of Sparton's Board of Directors and certain of its Board committees.

Lawndale believes that the public market value of Sparton, currently trading below Sparton's tangible book value, is undervalued by not adequately reflecting the value of Sparton's underlying businesses and assets.

Lawndale acquired the Stock solely for investment purposes, and Lawndale may from time to time buy or sell the Stock at its discretion.

The beneficial ownership of the Stock by each Filer at the date hereof is reflected on that Filer's cover page.
