I have no information about the Courtois 367A, but I played for 20 years on a non compensated Courtois mod 165. I can say that it was a very good horn, nice and warm sound, good intonation ( only needed correction on the partial sixth Eb), shorter valve stroke than on my current Besson Prestige, still impeccable construction and silvering after 20 years of daily use. If Courtois has maintained the constructive standards of eighties, I can certainly recommend the purchase.
Sorry,I got a bit of a mess in uploading photos.
