Anyone know how I could find out the date of manufacture on a New Haven (Mossberg) Model 283T - 410 gauge shotgun. The serial # is 113526-. Grew up learning how to squirrel hunt with a gun like this that belonged to my grandparents, but someone else in the family got the gun when they passed, so I just bought this one for sentimental reasons and for my kids to shoot. Any info would be appreciated.
