Enharmonic Tuba

[Highams]

Just up on ebay UK is a Besson Enharmonic Tuba, very rare, with two sets of slides, front & back. These were only made in 3 valve form and this is the first one I've seen.
For the Enharmonic system descripion, see my euph on my web page.

Here's the tuba;http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... 3743043215
