This is a  third issue of the Model 1+12 is known as the “Model 1+12 Single Action Revolver”. It differs substantially from the first two issues by breaking at the top (just in front of the hammer) as you can see it is not concidered in working condition. This would make a great project gun if you had the time to track down the missing part from what i can see the extractor is one part as well as the piviot screw. It is concidered an antique due to the age it was made before 1898 so I can ship it directly to your home. The barrel is just a tad over 3″. Should you wish to have more pictures drop me a line or text.
