A basset horn it is. Buffet Prestige, BC 1723 I think. Set me back about 3500 of your Earth Pounds. Which is about €15 nowadays.
Buffet brought out a new basset horn a few years ago - when I was living in Paris in 2003 I saw the prototype at the Buffet factory; I tried one out at the Musikmesse in Frankfurt last year and was damn impressed. They've recently changed a couple of details but most of them not as far as I can tell for the better - the fine people at Howarth (PROPZ!) had until this morning two of the old new ones and one of the new new ones and the new new one was really quite a lot harder to blow which we don't want really do we?
The dots nearby are of the Mendelssohn Konzertstück Nr. 1.
I'm playing in
Michaels Reise um die Erde by Stockhausen in mid-May in Vienna. There will be a couple of basset hounds in that but not played by me. But we have a Stockhausen tribute coming up later on where one of the composers wanted to write for basset horn and I thought it was time to have one up my sleeve so I went shopping. That does mean we can play some Mozart divertimenti in any idle moments between rehearsals...

Evan, martle, feel free!
