swathdiver - That is exactly my understanding as well. It apparently was in a previous auction and was not revealed as a fake. Perhaps the current seller was the victim and is honorably trying to recover as much of his investment as possible.
MY interest in posting MY question was simply "what WAS this" revolver before it was turned into a fake original Colt 1851 with early barrel address. Was it a Colt 2nd or 3rd Gen, an ASM, a Pietta, an Uberti, etc. and on what do you base your opinion???
Since there is a large skill difference in the barrel address and the serial number stampings, I am curious if the faker might have started with an already factory addressed barrel then added the frame inscription and serial numbers.
So far we have:
1. Berkley - Pietta 1851 Navy
2.
