My wife Karla teaches private flute and piano lessons. That is how I learned of these companies and contacted them in the 90s after seeing a flute magazine she subscribed to. Later on we ordered Karla a Brannen flute with rose gold faceted rings. Brannens let us chose the serial number 3333. The one with the engrave body and levers posted above is it. Here is the barrel joint and crown at the end of the head joint.
