Underneath the action just ahead of the trigger guard is the loading gate. The shells are pushed into the tube until the tube is loaded. Once 2 (two) shells are in the tube, press the slide release located just ahead of the trigger guard and to the rear of the loading area rearward and rack the slide rearward. This action will load one (1) shell into the barrel, allowing room for a 3rd and final shell to be loaded into the tube. To unload the shotgun, press the slide release rearward once again, and repeatedly rack the slide to the rear, ejecting the shells. Do this until the gun is unloaded.

Marlin started producing the 778 in 1979, production ended in 1984
I am not 100 % sure, but the research I have done indicates that they were produced from 1978-1984, with 1984 being the last year of production. The Marlin Model 120 is the continuation of the Glenfield 778 with some parts being interchangable.
