I just aquired a parts gun and am thinking of resurrecting it. Thought about getting it welded. Till I learnt model 94 Winchester has a cintered metal receiever. Post 64 Winchester model 94 with a busted/patched upper tang. This very rough bush rifle looks like I have base to work off. The 1964-82 sintered receivers were iron-plated so they would accept the various finishes Winchester was offering during those years - "Bluing" (it isn't), Pewter, Gold, Silver, Brass (all commemoratives), Case Colors (M94 Antique), and Black Chrome (NRA Rifle/Musket, M94 Classic & some commemoratives). The changes to the model 94 included: The receivers were no longer made from forged steel, they changed to a sintered metal casting process using an alloy that included graphite, nickel or chromium (actual recipes are not known, nor available from any source that I could find). Some of the screws were replaced with pins Many of the solid steel internal pins were replaced with hollow roll pins The final machining was changed, perhaps this was because the sintering molds produced a part that was "close enough"Some of the internal forged steel parts were replaced with stamped steel ones, of particular concern was the cartridge lifter/elevator While most of the changes did not in any way affect the performance of the gun, or the strength of the receiver. The testimony of its strength can be found with a lack of stories of post '64 Winchesters blowing apart. 1972 the sintering alloy was changed once more, this time the amount of steel was low enough that the receivers needed to be iron plated in order to accept bluing, the DuLite formula used was the original WinBlue/Oxiblack.
