Wm. S. Haynes flute #21214 was manufactured in 1950. It is listed on the Haynes website as a "Regular Model", meaning it is a closed hole flute. It has solid silver body and keys. Just got a C.O.A. (Clean, Oil and Adjust) in our shop. Please note that we have two if this model Haynes available, so you can come in and try them both.
