I would have bet DOM 1980. I have three Marlin 375s and they were all manufactured in 1980 - go figure. Marlin made a total of 16,315 Marlin 375s from 1980 - 1983. They sport a 20 inch barrel. One of my favorites!

The cartridge is very easy to load and brass is available sporadically. In a pinch, EA Brown offers 375 brass made from easily found 30-30 brass. I've used a lot of the EA Brown brass without incident with loads a bit hotter than factory.

Don't see these in the classifieds very often. Free Bump
