Those are cool old rifles sandpit
My brother has a really clean one (he's a life long Marlin nut).
His is old enough that it is marked "Browning Brothers, Ogden Utah" on the barrel.
That thing is surprisingly accurate with his handloads, although I haven't seen him shoot it in recent years.
Interesting cartridge carrier in that gun.
I'm thinking you scored too ; hope you enjoy it.
