Looks like you started with the typical "black army" Colt 1911 with very little finish left(as usual).

Interesting story on these guns. Expedited WW1 production with finish and machining shortcuts.
If you ever find one of these guns with the original finish intact,it must have been in a sock drawer for 100 years. Many where parkerized in arsenal rebuilds for WW2 use.
Great job. Good to know you do this kind of work.
