Sorry sent post before I was ready. Computer did it. I think I have figured out how to lower picture resolution so I can send photos. Serial # is 24432 don't think it is listed. There is no notch. Looks like an unaltered M1892 receiver I have two 92 rifles which are just about the same. Rounded muzzle and the stock is modified for oiler. Front sight does look right to me but I do not have another carbine to compare. I put a 96 carbine sight on the gun it had a 92 sight which I showed on one of the pics.
