Hello ! My friend also found a silver/platinum coloured very old Zchenkelaars eindhoven tenor saxophone i think its from the 1940-60 (serial number 04347) from a fleamarket. And I've owned it for couple years now. Has served me well after the maintenance but I'm wondering that does anyone else got the same sax? I mean same manufacturer at least. It's just a big mystery for me.. the whole manufacter and everything! I gotta ask from that url you posted also. But please if someone bumps on the Schenkelaars what ever tell me!
