This is my Flugal Alto, made by the German company Couesnon. It is in Eb, and takes a standard Alto mouthpiece. My experience is that most of these odd types of horn play poorly, but this one plays very well. Great tone, centered pitch. Unfortunatly, I don't have much need to play it though, as the bellfront design projects more than is needed for my jobs.
This silver horn is a 1906 York alto horn that is essentially the same thing as a FlugelAlto. Pretty cool!
