Bassoon - Puchner - Cooper Model

I have a beautiful Cooper model Puchner bassoon for sale. It has been played mostly professionally, and has a wonderful tone and sound. It has a high d key, full roller system, and is in perfect condition. There have been no major repairs made to the instrument, aside from intermittent pad replacement. It comes with a Puchner and Heckel bocal, and Walker Gig bag. The serial number is 65xx and is circa 1963-ish. I have photos upon request. I am asking $11,000 for everything.
