when was my gun made and what is its value

Question
I have a older Mossberg .410, bolt action, 3 shot, with an screw on modified choke, made in New Haven, Connecticut, model 183D-D, can you tell me anything about it?  

Answer
Nathan,

Your Mossberg .410 model 183D-D was manufactured between 1956 and 1960. It is a three shot take-down shotgun that was chambered for 2.5" and 3" .410 shells. It has a two shell fixed top loading magazine and weighs 5.5lbs with a 23" barrel. It also was available with a two choke screw-on system.

The gun in "good" condition has an approximate retail value of $75.

Thanks for the question Nathan.
