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.
The factors of 778 are: 1, 2, 389, 778.
