This is purely a "what if" sort of question, but the C melody saxes
being produced in China for Aquilasax made me wonder about something:

Is there any fundamental reason (such as completely different tooling,
or parts of an unfamiliar nature) why a factory that can produce a
custom-ordered saxophone would be unable to produce sarrusophones? If
they can, how large a production run does it take to make it a
practical idea? Aquilasax seems to be able to make it work with an
initial order of 100 C melody saxes, but oddball and un-saxophonelike
pieces like bocals might push up the initial tooling costs and require
a larger order.

To answer the inevitable question -- no, I most certainly do not have
the $50k or so it would require to get such an operation under way. It
just struck me as possible to do a new production run, though perhaps
not practical. Also it would at least offer the opportunity to
implement "modern" niceties in the keywork such as 1-and-1 Bb, and the
fork F#.
