The Marlin Glenfield Model 75 and 75C chambered in .22 LR are semi-automatic carbine versions that evolved from the Marlin Model 60.
Both have shorter barrels and come with sling swivels but no bolt release lever by the trigger guard.
The 75 has a 9+1 capacity and the 75C has a 14+1 capacity.
Model 75 production ran from the late 1960s to about 1975 while the 75C was produced after that into the early 1980s.
