GENERAL PARTNERS IN GENCORP <GY> PROXY FIGHT General Partners, the group tendering for all GenCorp Inc shares at 100 dlrs each, said it has started soliciting proxies against GenCorp's proposals to increase its number of authorized shares outstanding, create a board with staggered election dates and eliminate cumulative voting. The proposals are to be voted on at the March 31 annual meeting. General Partners, a partnership of privately-held <Wagner and Brown> and AFG Industries Inc <AFG>, made the disclosure in a newspaper advertisement. The partnership has already filed suit in U.S. District Court in Columbus, Ohio, seeking to block a vote on the proposals and to invalidate GenCorp's defensive preferred share purchase rights. General Partners asked shareholders to either vote against the proposals or abstain from voting on them.
