Thought I would share my latest acquisition this has a last patent date of August 19 1913
Smooth mainspring housing... I finally got to shoot it today and let me tell you she is still accurate! I was making minute of 18" gong shots out to 100 yards one handed. What makes this one special is that a friend gave it to me a gift! That is right no fee.
The only part that has been replaced is the hammer. the original was a little worn. It does wear WWII grips but I can live with that!
