I just purchased a Thein Contrabass made in the 1980's. This mpce was included in the sale. It has a 31.00 mm inner rim with a wide semi round/ semi flat rim. It is rounded into the cup. It has a very deep cup. The blank is on the lightweight side The engraving just states "THEIN" nothing else. I have other mpcs I prefer. New these are $359.00. I am selling it for $285.00 with free Conus Shipping.
