This question has been kicked around on the boards before, with no satisfactory answer. The closest I can come is that there was a WWII sub contractor that made M1911A1 triggers for Colt's, Ithaca, and Remington Rand called the Yawman Metal Products Company. (See Clawson's book, 'Colt .45 Service Pistols, Models of 1911 and 1911A1', pg. 332.) The triggers were marked with a 'Y'. Once a subcontractor was chosen to produce parts, a mark was assigned which was not used by other producers. Frank has stated that he has not been able to find Yawman listed anywhere in his extensive research as having had anything to do with M1928/M1928A1 production. Another theory is that this was an ordnance inspector's mark, and not that of a sub contractor at all. I have an 'S' marked 'bright' M1928A1 bolt with this enigmatic 'Y' as well. This mark will remain a mystery for quite some time to come, I'd think.
