I have this 1914 vintage York Eb tuba for sale. Where you might all be interested is this horn seems to need alterations as the low/high pitch interchangeable slide does not lock in the pitch. Either I’m 25 sharp or flat. Now, that could be that I don’t have a great mouthpiece for it. My first teacher was Bob Rusk. Sadly he is not with us any more to work his magic. Maybe you have a tech who could resolve this issue.
In any case, this is a great horn and I think rather rare.
