Marlin model 60 when I was 10. A friend of my parents needed help on a siding job during the summer and the Marlin was my payment for helping him.
It shot great to start with but then tended to hang up a lot. It might of had something to do with me filling down down the sear to make it fully auto? It would spit out 3 or 4 rounds and then hang, but those were a fun three or four rounds!!!
