The more Ive been reading the more I discover. This 1911A1 RR/Colt 1943 on loan is a mixed what I believe could be a arsenal rework at one time. The book talks about arsenal identification/inspection marks and also the lack of. AA RIA SA and others etc... Do these marks qualify as others and what others could they be or what else can they be?
top mark is the letter O or the number zero and the lower mark is what looks like either a open 6 or the letter G. your thoughts please.
