mossberg 410 model 183d-c This shotgun has been in my family since way back when. It was the first shotgun that I ever fired. It was lost for several years and not a single family member could remember anything about it at all------WELL about 5 years ago My uncle passed away and guess what we found in his closet out in Utah-----This was my Grandfathers---and my uncle left a not inside the case telling me to make sure and keep this in the family. I cant find out a lot about this weapon other then they made them up until about 1970. Its a cip fed colt action 4-10.
