Toward the end of WWII the three manufacturers were ask to submit 250 pistols with fully hardened slides to Springfield Armory for testing. The testing ended about the time the time WWII ended, but it was decided that all future slides would be hardened. No more 1911A1 pistols were manufactured, but the slides purchased by Ordnance from that time forward were hardened.your second picture shows the heat treatment areas on the slide, what year did they do the whole slide? very nice package, thanks for posting, these early post war models are some of my favorites.
