I listed this instrument on eBay today. This treasure is a very hard to find professional metal Bb clarinet made by Buescher in 1928 (estimated). It has a tunable barrel and screw on bell. Anderson plating did the replating. Mills Music’s Steve Nelson did the complete overhaul with a fabricated right-hand thumb rest, new pads, corks, and some springs replaced.

Update: It sold the next day with the buy it now price. Thanks for looking.
