I recently acquired an old spur trigger revolver that has been completely disassembled. There are only 2 identifying markings on it. It says CROWN across the top and the numbers 161 under the left side grip. I have searched the internet and found a couple that resembled this one (Iver Johnson) but can't find any schematics for putting this thing back together. Any help at all would be appreciated. The cylinder mics at .32 and the barrel mics at .310. Gun looks similar to the complete gun pictured.
