That trigger and trigger guard look like mid 50s to mid 60s to me. I want to say I've seen a mossberg or two that looked a lot like that. I wonder if that's who made it for sears?
It is Mossberg? made.? Nice little rifles youi could once buy from mail order.? Not worth a lot of money but a handly little camp gun.? I'd guess late 40'sor early to mid 50s.? Monty
