(Helen) According to information that I have archived from an old Kessler & Sons webpage, back in the day when they were still a B&S dealer:
"Part of the JA Musik Group, the Antoine Courtois name is mainly associated with professional brass instruments.
Courtois is the Oldest of all current operating musical instrument manufacturers.
The Courtois saxophones are actually made by B&S, another company in the JA Musik Group.
The Courtois saxophones are identical to the top model B&S Medusas.
JA Musik has decided to discontinue the Courtois name on saxophones and has offered a small quantity of these saxophones at an unbelievably low price.
These handmade German horns at this price are by far the best value that you will find on today's market... "
You might notice that I'm posting a few horns in here that are actively for sale.
I'm doing that for a few folks that have been long-time contributors here.
The standard disclaimer applies: they're not my horns, I don't claim they're good or they're in perfect shape, etc.
If you want to list your horn, e-mail me at thesaxinfo-at-gmail.com and we might be able to work something out.
