Thanks Guys, The web sites helped, and after ahole lot of notes, everything checks out to be org. without the rebuild marks and without the "s" for service I'm still getting different finishes, mines blue some say thats right some not and the barrel seems to be a colt, it has a "c" inside a "[]", can't find if thats ok, it is not listed as a barrel that RR used but both have a listed 1944 date, so I still have ? I guess that means some more reading and writing
Thanks Again
