I thought this gun was a Pocket model (5 shot). As I conclude now, it is a full size Navy revolver (6 shot). Sorry for my assumption.
Well, yes and no, your first implusle is better than you think
It's a Pietta that looks like a recreation of a real revolver but as far as I can tell, it
isn't. To me it seems like a cross between an 1860 Army, a pocket Police, and a New navy
Pietta called them "Colt 1862 NY Metropolitan Police" models, but as far as I know, that never really existed, and the closeset Colt model that really was made was similar, but not quite the same. if it was a Colt that was really made it really
would be a 5 shot in that case, and smaller, too, so I totally see where you thought it was 5 shots and a pocket model
I took the barrel and barrel from my Pop's 1851 Navy (another Pietta) and they fit. I put the frames side by side and they look identical in dimension. I wouldn't fire the revolver in that configuration, but the parts fit. I think Pietta wanted another model in the stable and dreamed this one up, using a full size frame from their 1851 model
It seems like this revolver is a believable version of a revolver that was never actually made by Colt. Maybe Colt missed the boat on it but I can't say they really made one like this. White elephant of sorts, but a good looking one, and it shots well. I think the cap and ball revolvers are special
