I'm leaning that way as well, although it's an early serial # to be 6 shots, which it appears to be. It would be helpful to have a couple more details such as the caliber, the barrel address and the number of shots (for sure). The butt serial # is also very unusual to be strung out like that. Usually they are close the screw and oriented across the short dimension.I believe the precussion to be a 1849 model Colt.
Likely an 1849 Pocket then, or a repro pending the resolution of the serial font and placement on the butt.Okay lets see there is something on top of the barrel on the percussion revolver but its very hard to make out right now with out further cleaning, the caliber is hard to determined but estimate it to be around .30 and it is 5 shots. Not sure of the term "barrel address" what does that mean?
