RE: antique ammo in original boxes
For anybody who collects those, you can find a ton of info online and places to buy those old boxes and shells with a search. I have a couple ammo cans full of old shotgun shells from the same era, and some older too that I picked up for a steal. Depending on the caliber can be worth a ton of $$$$. Best of luck to you either selling or buying them.
P.S.
I'm not selling mine. They are going to be used as decor in a game / hunting lodge type den.
