Interesting - Except for Enfield's & some other military rifles, factory boltgun's chambered for a rimmed round are few & far between.
I wonder if it's an early Husqvarna, that someone bored out to .429" & chambered in .444 Marlin, most likely a "cock-on-closing" Mauser 1896 type Husqvarna (which were made in 6.5x55 & 8x57R).
