OK, this is a well traveled Mauser, built by FN in Belgium as a contract for the Colombian military, this is the last military contract bolt weapon made by FN. FN was already set up to produce the K98 so postwar it was only fitting to use the equipment to produce contract weapons. The FN49 was starting production during this same time. This is one of the few Mauser's originally factory chambered in .30-06. It is also set up to us the .03A3 stripper clip, because the US was supplying Colombia with ammo. It is also the reason for the notch in the rear receiver.
Now, this is were the fun starts, this rifle is no longer .30-06, it's 7.62 Nato. Colombia surplused or it was a contract overflow and some rifles ended up in Israel, where they were rebuilt and rebarreled. The stock is a surplus German stock Israel installed and denoted the caliber in the butt stock, also the butt plate is painted yellow. The bolt on the orginial .30-06 has a straight handle, when Israel worked them over, they bent the bolt handle as I understand. I don't have a close up, but the crossbolt has a German waffenampt stamp as well. To add a little more confusion, the barrel has a British proof stamp, it has a BNP 7.62 20tons with crossed swords.
So, it started life in Belgium, ended up with a Colombian crest, has Israeli rebuild features, and got British proofed along the way.
And, you can have a true military issue K98 looking rifle in a very modern caliber.
