This Marlin manufactured first variation inner magazine tube assembly is for the earlier Glenfield model 60 semi-auto rimfire rifles manufactured before June of 1975 and is in very good condition with light wear and a tarnish to the brass tube. If your rifle was manufactured in 1975, it will have a serial number that stats with a "25". If your 1975 manufactured rifle has the band type front sight then this magazine tube assembly is correct for your rifle. If your rifle has a ramp front sight which mounts with a large head straight slot screw, then it was manufactured after June of 1975 and uses the late variation inner magazine tube assembly.
