I also have something I'd like to identify. I have a CD of, yes you guessed it, chalumeau music. The player (Christian Leitherer) has performed a piece labelled as "Händel - Sonate F-Dur op. 5/1". I haven't had any luck actually finding this piece and would very much like to. I did find a recording of the Handel op. 5/1 but this didn't actually seem to be it although I don't remember how reliable the scholarship was on the other recording...
Anyone out there (strina?) who knows what this piece is? I've posted the first two of five movements, an Adagio and an Allegro; the other three are Largo, Bourée and Menuett (it says here).
Nice disc by the way. I heartily endorse it. It was actually what got me interested in investigating the chalumeau rather than just listening to it so it has a lot to answer for.
