Love this site and this is my first post needing some help! I was given my Grandpa's Marlin 410 lever action ser#1943 shotgun, those given out by Marlin for buying company shares in the late 1920's. I was needing to know which model action it was built on and some help with parts. Everything is working but loading and ejection is sporadic. I would like to replace the ejector and magazine tube spring. Also the butt plate looks like it was carried resting on the tractors exhausted manifold when haying (Grandpa used it for sage chicken, badgers, skunks and occasional close up Parriedogs). If I could replace those three parts I would be extremely happy. Any info about this little Marlin lever gun would greatly be appreciated.
