Howdy. This 3rd Model Hammerless was made somewhere between 1909 and 1941. Apparently, much of Iver Johnsons archives were lost to the paper drives of WWII, so serial number discovery is not straight-forward. Also, their serial numbering system was not always sequential.
The owl? That's Iver Johnson's icon, and it was on many thousands of their grips.
I bought one like that at a flea market for 85 dollars. Was supposed to be unfired, but it was all scratched up from people taking the cylinder out improperly and scratching it on the latch. I carried it in the woods for awhile and shot it some, then the trigger return spring broke. I couldn't find an exact replacement so I bought a larger one from someone's scrap box in a gun show and modified it to fit. 'When I put it back together the trigger went back and something slipped and it wouldn't return. I'm thinking I messed up when I re-assembled it. :shock:
I finally gave it to a friend of mine and told him to find someone that knew how to work on them. I don't think he's done anything with it yet either
One of these days I'll find the right "Round To It" and maybe fix it right for him, if I can find a manual 8)
