I bought a used flute recently and I'd like to know more about it. The flute head is silver and has 'silver head' and 55 stamped on it. It has a B foot. The body is stamped E. L. Deford Elkhart underneath a diamond with ELD inside of it. However, there is no serial number I can find at all. Or any sort of model number. As far as I can see, the E.L Deford Elkhart and the diamond logo is the only thing the body has stamped on it. The body is closed hole with offset G. The body and foot are a bit tarnished, but I'm not sure they are solid silver or plated. Can anyone shed any light on this for me? Thank you.
