Weird question. I have a Pietta 1851 navy .44cal and a Pietta 1860 army in .44 cal. I ordered spare cylinders for each. When I got them the scenes on the engraving look the same to me. Is the engraving on the cylinders supposed to be the same? I went and looked at the cylinders that came with the guns originally and they seem to be the same as well. I guess I always assumed it was different engraving. Maybe not. Is it normal?
