Sort of. First, quoting from the IDRS article, which is quoting Kurz and McBride from Buffet, Primarily because I've written SOMETHING about the contrabass Sarrusophone, I've been designated "expert" status and people are e-mailing me. Used to be once a year. Now it's once or twice a month. So, a gentleman e-mailed me about an Evette-Schaeffer Sarrusophone he had and wanted a value guesstimate. I initially responded that a) I didn't think E&S made a Sarrusophone because they had the contrabass saxophone and b) that "Sarrusophone" was a family of instruments, so just saying, "I have a Sarrusophone" doesn't help me with the value. So, I asked for pics and got 'em. It's ENGRAVED E&S, but the serial number is 12x (blanking out the last number for "security"). And looks like a Conn 16V. I've asked the owner to check for the Haynes tone hole patent on the horn. I think he'll find one. I'll try to post some pics, later. I THINK I have an idea where that 1907 E&S catalog is, too.
