The Ted Williams 200 shotgun was manufactured by Winchester and was the same gun as their Model 1200.
Given the lack of information on condition; 1-200 USD
200 or so.
Double barreled shotguns are manufactured in several countries.
Internet auctions, gun shows, gun shops, want ads.
The value of a Ted Williams 12 gauge single shot, shot gun is determined by the condition it's in. If in excellent condition this gun may be worth up to 400 dollars.
50-200 USD
