Jim, thanks for your effort. I do know for a fact that my Dad bought it new in the late 50's because I remember when he bought it. He and my Mother use to let me take it out and shoot it when I was about 17 and then later they said the gun just dissappeared when I would ask to shoot it again (I think they had second thoughts about a kid with an automatic pistol). After my Dad died in 1988 my mother ask me to come over one day and that she had something for me. There it was, the pistol that they had lost and I had forgotten about all those years and she wanted me to have it.
I wish I could give you more info on it but what I told you is all that's written on the gun. It does have smooth wooden grips and shoots absolutely wonderful with never a jam that I can recall. I shot it the last time afew years ago and am going to be shooting it a little more here shortly. Thanks, Dave
PS It does have fixed sights
