I just HAD to list this! It looks like a fun horn and is pretty cheap. There is some lovely scrollwork on it, and while the seller doesn't know much about it, the valve slides look like this is a Bb instrument. It's either kind of a conical baritone or smallish euphonium or whatever else they might have called it then. European. Starting bid is $240 and buy it now for $350, with only $25 for shipping.
