I NEED A 16 INCH CORK TURNTABLE MAT

There is an outfit from Portugal that sells a cork/rubber 16" mat, die cut, for around 25.00 US plus shipping. They claim that they will do other versions. Might be worth contacting them. They are on E-Bay. 

Senor Wences, with a curl over the "N".  Not "senior".  Was having a senior moment.

I knew what you meant. 😊
