yes, I am sure you are absolutely right. The only "lucky" provinance I am hoping for is that the arizona territory was factory engraved (I think that is about a 10% chance).
I don't think getting a colt factory letter for the primary frame number would not hurt and would say (possibly) where it was sent or to whom.
but, I have all along after seeing it beleived that I will be lucky just to have a 45 Colt 7 1/2 barrel 1st Gen
