I will very much appreciate the analysis the experts could do on this gun I had from my father...it was bought at the begining of the XX century by the Venezuelan Gvmnt. so I´ve been told. Probably, please correct me, lost part of the trade marks because of the nickeling I believe my father had it made. I thought it was an I J because it doesn´t have the side latch for safety. but then the screws in the I J are in the left side of the gun...The only marks I´ve found are at the butt of the grip and behind the barrel latch, in both the number 17860. If u need any other information or pictures I will gladly send it...I'm selling it and want to know the right price for it
