This belongs to a coworker of mine. It is stamped Winchester Model 02-22. I have done a little research and found that it is actually a model 1902 and I think in 1919 the changed it to the 02-22. But I can not find anything on the threaded barrel. This also also has a metal butt plate which from what I can find would preclude the model change to the 02-22. If anyone can shed any light on this we would appreciate it.
