I recently inherited an old Savage 430 16ga O/U. I've been trying to find some info (yrs of production, parts, etc.) on this model but there isn't a lot available. Gun had been sitting in a gun safe unfired for at least 30yrs that I know of. I want to completely disassemble and refinish the wood, barrels and receiver. It's a tank of a gun, but would like to use it for dove hunting. I've removed the foregrip, but can't figure out how to remove the barrel assembly. Anybody have some words of wisdom for me? Thanks
