OK guys i need some help. i was given a .410 single shot for my 12th birthday back in 1997 and i am trying to find out some info about it so i can replace some parts. i was told when I got it from my grandad that it was old but i dont know how old. the only markings i can find on the gun is the serial number and the word GREENFIELD stamped to the side of the gun. i searched for greenfield online and didnt really find anything to help, so i hope some of you can give me some.
