[Dixielandjazz] Couesnon Valve Trombone

[william crist]

Several months ago I posted an inquiry about Couesnon Valve trombones
and haven't received many replies.  I wonder if some new listmates might
have any information on them ?
I purchased this horn in the sixties and can't seem to find much
information on them.  The serial number is in the 50000 range.  Does
anyone know of a serial number list for these horns or any other sites
that might have any information on them ?  I tried Google but can't come
up with much.
TIA
