the coast to coast rifles I have seen have had the charging cut out , the place your thumb goes when feeding them with a stripper clip it is a dip on the left side. These are not typically seen on post war Mauser rifles , but were the norm on k98 recivers used in combat.
a lot of these rifles were surrendered at the end of the war ,
the NRA chart for rifles sold as a store name does not list the Coast to Coast model 100.
is it possible Husqavarna rebarreled and stocked these rifles , it is possible , if it was a Huquavarna barrel I would expect a H crown proof marking on the barrel.
there were a bunch of shops buying up surplus mausers and making hunting rifles of them almost exclusively in 30-06
the US was in the process of re-barreling millions of rifles in arsenal rebuilds during and after the war and they almost all had 30-06 in common so the industry was set up to makes 30-06 barrels , it wa sa popular hunting cartridge and amunition was plentiful
