I received this beautiful ivroy colored tube ring several years ago as part of the deal for an older model Aries 10" Mak-Cass. I have never been able to ascertain who the manufacturer of this tube ring was and there are no logos or labels on the ring. It is in beautiful condition as you can see from the attached photos with no scratches or dings to speak of. The tube ring has a clean black felt lining on the inside. Measurements suggest that it is European in origin but that is just a guess.. For example, the 3 threaded holes shown on the top side are separated by 30mm center to center. I believe that the threads are M5. The 4 interior thru holes on the base side are separated by 35mm center to center. The tube ring has a nominal inside diamter of 30.25cm and its width in the short direction is ~12.5cm. I will try to answer any other questions you might have. I am not using this tube ring and hope that someone out there can put it to good use.

Price: $300
