I recently bought an unfired Uberti Walker. Outwardly, it is in perfect condition and the fit/finish is exceptional. I tried to disassemble it for cleaning, but I can't get the barrel off the frame. I removed the wedge and tried to pull the barrel off, then I used the loading lever as a persuader (piece of wood between it and the cylinder) but no dice. The cylinder turns freely. I can't tell if the gun is bound up on the cylinder rod or the two alignment pins. Before I start beating it with a hammer, do you have any suggestions?
