I have this gun. I believe it was 1965. It's the same as a Mossberg 351C. I found new firing pins for it on e-gunparts.com. Yes, that is basically the Mossberg 351C. Under the Mossberg name, they called it the 'Jack Rabbit Special.' The gun is the 351K with a shorter barrel and carbine styling. Should have a stained hardwood stock instead of walnut, and no serial number. If it IS serialized, it is post-1968. sales@countrygunsmith.net

If your Mossberg is a bolt action shotgun, about $80-100. These are well built utility grade guns- no major collector interest, but durable and reliable.
Mossberg made all their rifles in the USA.
