[Trombone-l] Antique horns

[David Leep]

Adrian,  I think you are right about the one-valve-at-a-time, but notice
that the branch paths at the valves appear to be not extensions but
shortcuts -- that is why the the tubing goes twice through (once out from
the mouthpiece, once back toward the bell) for only one set of valve crooks.
(That puzzled me too at first.)  If I'm reading the picture right, the
valves would represent positions 1 through 6 (and if for any reason more
than one valve was pressed, only the lowest-numbered one would count) and
all-valves-disengaged (I hesitate to call it the "open horn") would be 7th.
What fun!
