The turntables on all the KLH models, except for the Model 35, were made by Garrard, they are essentially an OEM version of the Garrard model 3000. They had a custom version of the tonearms, a white base and KLH specific platter mats. The very first model to use the turntable was the Model 11, and the mat was black, later all the models got the white mat that you have, and toward the end of the run they switched to the gray mat that's on mine. The problem with the lighter mats is that whatever material they used to make them didn't age as well as the black rubber mats. So most of them have dried out to some extent, they are no longer very pliable and most have severe cracks. How does yours look?
