To disassemble a 1847 Walker USMR revolver, first ensure the firearm is unloaded and remove the cylinder by pushing the cylinder pin out. Next, remove the grip by unscrewing the screws on each side and then detach the frame from the barrel assembly by removing the screws that hold them together. Carefully take out the internal components, such as the hammer and trigger mechanism, while noting their arrangement for reassembly. Always refer to a detailed schematic or manual for specific instructions and safety precautions.
Probably Uberti. Look on the underside of the barrel for manufacturer's logo/markings. The "USMR" marking is historically accurate and appeared on original Walker revolvers. Stands for 'United States Mounted Rifles' which was the regiment of the designer. sales@countrygunsmith.net
