I recently acquired a H&A safety police top break revolver. Its chambered in 32 (I believe S&W) however I'm not positive as to if it is black powder or smokeless. Beneath the grip is the serial number 806 and the patent date is Aug 21 1906. It's not perfect and I don't really care what it's worth, but I'm looking to find out any information regarding the ammo for it and any solutions to the cylinder not rotating when I pull back the hammer. Now to clarify, it will rotate on each chamber of the cylinder but one. It attempts to, but does not rotate to the next chamber. Any information regarding those items and disassembly/cleaning is welcome. Thanks for taking the time to look this over.
