http://www.ebay.com/itm/371567447916?_t ... EBIDX%3AIT" target="_blank" target="_blank" Bb, Eb ? Tuba or euphonium? It looks similar in size to my Amati ABB 223.

Pretty sure it's BBb.

And also quite small. If 2/4 tubas exist, this probably such an one.

These actually can hold their own pretty well, in my opinion.
