I have recently come into contact with a rifle that I need help getting some more information on. At first examination action appears to be a interarms mark x. All proof marks on the action are a "crown over BNP" Left side of barrels is stamped with the caliber (7mm rem mag.) the crown over bnp, another proof mark I can't make out and A.D. Heller Inc. BALDWIN, NY. Right side of barrel is marked with FIREARMS CO. ENGLAND Top of barrell is marked ALPINE SUPREME. The gun is supposedly very accurate with it's nickle and dime tasco scope, however, I have not confirmed this yet. there is no brand marking on the action however on the left forward part of the reciever is the marking MAG-288XX. Any and all help would be greatly appreciated in helping me furhter identify these companies and gun.
