OK, am I missing something here? I don't see a mark anywhere that says USFA beyond the seller's description. The top of the barrel says Colt, and the marking on the side matches the last roll type engraving Colt used, altho the font doesn't look quite right, but I may be wrong about that. I hate to say it but it looks more like someone cobbled together an ASM frame from their last production of using up parts and maybe added the Colt address on top of the barrel. The fit of the triggerguard to the frame, looking at the serial number picture, is atrocious. Like I say I may be wrong but that revolver doesn't look to me like it was ever near USFA's production floor. At the very best this could be a reworked Colt, but for that it was either renumbered or someone found an old frame in the bottom of the bin, in which case they've destroyed an otherwise very collectable piece. Sad.
