Got an e-mail today: My response: Yes, a contrabass Sarrusophone would be better than a contrabassoon for a saxophone player, as the Sarrusophone has approximately the same fingering as the saxophone and single-reed mouthpieces were available for it. Saxtek did sell his horn in 2007. Sorry. An Eb contrabass Sarrusophone in good shape is an investment of $6000 US or more. In perfect shape, you're talking around $7500 to $8000. They're also somewhat uncommon, which tends to justify the price. A brand new, lower-quality Amati contrabassoon sells for close to $8000 and a Fox retails for close to $25,000. A high-end USED Heckel contra sells for $30,000+. I don't have any specific information on the Buffet that you're looking at, nor can I tell you anything about its quality. I did some brief Googling and found that Evette-Schaeffer Buffet-Crampon made "French Fingering" contrabassoons. I do not know how different these are from normal bassoon fingerings. Please also note that an instrument that is as old as what you mention (and note that if it's stamped "1900", that may just be the date that it won an award, not necessarily when it was manufactured), it may be HIGH PITCH (A=457hz) or FRENCH PITCH (A=435hz) -- both of which may not be what you want. Most modern instruments are low pitch (A=440hz) and most European orchestras use A=442hz. If it's a high pitch horn, it'll be very out of tune with modern instruments. I can also say, based on my brief research of Heckel instruments, that sometimes double-reeds were made in odd pitches. You don't want to spend several thousands of $ to find out the horn won't play in tune with your ensemble.
