I finally opened the package left to me. Inside was a numbers matching , 1456, Warsauu, PKG, 1929, Mauser K 98. I am trying to find were I might start looking for correct information on this rifle. I believe it was purchased by Poland shorty after the first world war, when Germany had to see off all it's military items. The problem is that my serial numbers are very low and are documented by Poland, in any publishing's that I can find. Any help would be much appreciated.
