Shotgun Sports had a good article about the Win 101 from its genesis to its demise this past summer. My question is for 101 afficionados: How much stock dimensional differences occured through the ages? Are the dimensions and sight plain vastly different between the Trap Grade, Diamond Grade, etc., and where the dimensions and sight plain different through the years of different manufacturers? And, didn't Nikko produce a 101 for a year or two?
