I bought this on eBay recently to test on my TD150. It is in as-new condition and works exactly as it should.
The centre is cut out for the 45rpm spacer on a Thorens TT - TD150, TD125, TD160 etc

The reason I'm not keeping it is I have a second Herbies mat with standard spindle hole, which I have decided to use in combination with a SDS metal mat. Mind you, this one looks v nice when set up on a Thorens deck and does all the good things Herbies mats do
