I am 70 years old and when I was about 12 my grandfather gave me a mossberg G4 single shot 410. Someone sold one on a gun auction site, not GB a while back and said it was the first shotgun made by OF Mossberg. I think that is probably not right but I can't find any real info on when it was made or much about it at all. I am planning on passing it on to my great grand daughter. I carved my initials in the stock when I was about 14. Now I am thinking about stamping my grandfathers name, my dad's, mine etc in the stock with machine stamps. Is that stupid or Ok. The gun is still in good shape an could be fired with not trouble. Amazing old gun. Shot lots of rabbits with it years ago. Even shot a couple of Jack Rabbits when they were everywhere. Tried to shoot pheasants but not enough power to bring one down. It isn't marked but sure it is only 2 1/2 inch shells I shot a lot of 3 inch shells in it but only roll crimp, the others would not eject, not enough room.
