42M-B with United States Property on receiver and barrel.
Ser # 19643 stamped on barrel and receiver.
Has all the standard Britt proof marks, no extras.
Walnut stock with complete trapdoor buttplate,
Barrel is D&T for rear sight, has a 101 sight on the front with original hood, #4 sight on the rear with correct, original standard peep.
Has a dustguard.
Both sling mounts, non removable rear, correct and a period correct looking leather strap, no markings.
Receiver D&T'd for standard scope mount, correct trigger guard and safety buttons.

And finally a trigger that is so nice it brings tears to your eyes, about the best of any Mossberg that I own, a very good shooter, excellent bore. It will never be for sale, my Son will love it when I'm 6' under.

My Best, John K
