Well, I bombed out on this one. I looked at both of my belts and there is nothing to read on either tag. It's all faded out. All I find is the following:
On the buckle itself: TK-810 & TK820 MFG For Superior Ind., Van Nuys, Ca. So with that took the measurements and both the left and the right are the same length. The short side is 22" L & the long side is 31" L. And they are 2" wide. Mine are a medium brown but what does that mean except that my carpet is tan or light brown.
Hope this will be of some help. Richard
