I see no one has mentioned these yet I have two of them a Marlin branded one and a Sears branded one. Both are tack drivers and a trigger job is easy with a spring out of a bic lighter (the long one in the middle of the lighter cut to size) and lightly honing the sear. I have 2 pound triggers on both of mine. I paid 50 for the Marlin branded one from a friend and I paid 130 for the Sears branded one at a gun show. Very nice bolt guns for the money. These were made from the late 40s to the early 70's. The later ones had the grooved receivers for scope mounting. Both of mine have that feature. They both are tapped for peep sights and neither of mine had them I think folks take them off and sell them as you can get almost as much for the peep sight as the gun.
