i seen a scope base for a new englander on the(e bay) and it says 1991 or later I've seen you guys talk about early 4 numbered guns.....if i look at the barrel will i be able to tell the year? i got 3 new englanders and a extra barrel two are shotguns, ones a 50 cal pitted i'm hopeing to the base will fit on this one, the other barrel a 50 too but the bore like new but the gun sat on a wall and the blueing discolored my plans are to get it dipped in winter camo(all the medal parts and have the walnut stock) thanks for any info
