I purchased this Dolnet saxophone from my instructor back in 1968. He used to live in France befor the war. When the war broke, out he left France and he took several Dolnet saxophones, which he had in his possession, with him. He told me that he used to sell Dolnet Instruments on the side. He was a world renown symphony clarinetist. He passed away in the 1980s at about 80 years of age. I am trying to find out information on the saxophone. I found the serial number #42561 Dow by the D key. On the Bell it says Dolnet II made Paris France made. The horn plays a little bit flat. Not sure I can fix that at all. Just trying to find out information about it. It is like brand new condition. I bought sax in 1968, I was going to be a music instructor but military called and 1970 and stay they till 1978. Lost interest and never played again, that is till now. I started playing again now that I am retired and got curious about the origins of the saxophone. My instructor told me the factory was destroyed some years later.
