This is another one that I picked up at the auction this weekend. It's a J Stevens Tip-Up in .22 LR. They made several models of these but I think this one is an Offhand No. 35. This model was made from 1923-1942. In 1929 they change to a stamped trigger guard like this one has. Based on the serial no. I think this one is from the early 30's. I need to find some grip screws for it. I doubt they used socket head screws back then.
