Although similar, the tooling for a sarrusophone would be different
than for a saxophone. Since the instrument is larger (several times
the length of a straightened C-Melody) it would also be quite
expensive. There is also a lot of trial and error work to get a new
instrument working and in tune and the tooling must be changed as
problems are corrected. (note the announcement that the "intonation"
problem of the Aquilasax has been corrected).

Shoud you want a new sarrusophone Orsi will make one for you, and
probably make slight keywork modifications if you request them, since
it is a custom instrument. They already have the tooling and just
need to dust it off when they get your order.
