Ian, who blogs at "Forgotten Weapons", and at "Gun Lab" has a .pdf of an article By Colt production engineer, E.P. Herrick, and published in Machinery magazine for December 1942
His full post is here Looking at 1911 Castings | GunLab
The link to the .pdf is at the bottom of the post.
It's a pleasure to find first hand information, rather than endlessly copied and un attributed gossip.
The article includes a very interesting table of the steel specs used, although the spec for the barrel steel is different in the table (4150) and the text (1350).
Enjoy!
