I think it is 1920 commercial. True?

I don't see any rebuild marks and all numbers match. I guess they could have serial numbered the barrel during a rebuild. There is no magazine for it. There is one strange mark on the barrel and one on the trigger guard. I could not identify them and thought that it was just in proccess markings from manufacturing. I will try and get the macro working on the camera and post here. I found no markings on the right reciever front. Thanks for helping. I don't know if I mentioned this before, but this was a bring back by my Uncle from WW2. My father said he remembers it being brand new when he saw it in 1945. Now it's a little worn.
