What are the ballpark values for an old Sears Ted Williams Model 300 (12 ga; adjustable choke?) shotgun? I think that is the correct model number. Does anyone know? My Dad has one and I have loved shooting that shotgun since I was about 12 or 13. Very smooth. I missed one in a pawn shop several years ago for about $130. I haggeled too long and it got sold. I have seen a couple online for a little under $200 lately and want to get one. Just want the best price.
