Belt for Thorens TT

Hi Guys,

Need some help tracking down a new belt for my Thorens table.

It is a Thorens 316, but I know there are mkI (1985-88), mkII (1988-91) and mkIII (1991 on). No clue which mine is other than the Serial number is 15332.

The old belt which I think is original is 0.1875" wide (which is right for a thorens belt) but circumference measures just over 22".

The belt is loose but is it right to just go with the nearest official size I see listed which is 21.6"??

thanks John
