That's Gregus Pal from Hungary. I bought a tenor tarogato from him a few years ago.
Yes, that's an Eb clarinet at the front. I didn't know he'd made one of those. That's an octavin that he's holding.
The alto tarogatos on the left are copies of a very rare Stowasser that Scott Robinson measured for him. The ones of the right I believe are copies of a Shunda instrument with a simpler mechanism and smaller tone holes. As I remember, those ones only have a single octave key (like Shunda's soprano tarogatos) and are very difficult to play.
