It should be a straight swap and i believe manufactured in Brazilfrom the 1930s thru 1990s.
Current commercial "Springfield Armoury inc." 1911s are/were rebadged Itajuba pistols.
Purchased Colt 1911 and 1911a1s from the early 1920's. Set up licenced/unlicenced production possibly as early as 1927ish.
lots of discussion on the internet:
