An Argentine (Hartford-built) Colt I had rebuilt. When I got it it was painted green, had pink aluminum grips with FLAMES, beavertail, target sights, etc.
Vulcan Gun Refinishing in Ontario did it all for me and finished it with black oxide. The hammer is a bit funky but I haven't found one to replace it with yet. All serialed/Argentine stamped parts match except mag, and obviously incorrect hammer.
I wish I could find a before picture.
