My LGS has a custom 22-250 on consignment and I'm considering it.
It is a 22-250 built on an argentine Mauser action, heavy barrel, the deepest bluing, sitting in a gorgeous walnut stock. I can also see the word jaeger stamped on the trigger, if that helps. The previous owner is deceased and its origins are unknown.
Below are a few pics of the makers mark and any help is appreciated. There is one in the barrel and another behind the pistol grip, on the underside of the butt stock.
