Does anyone know if the U.S.Q.M. instruments were High Pitch or Low Pitch around the turn of the Century? Were they all of the same standard, or were some HP and some LP?
The King BBb helicon has a four digit serial number, and one of the valves is stuck, making it impossible to check against a tuner.
There is no "HP" or "LP" engraved anywhere, but there is a U.S.Q.M. engraved near the H.N. White name.
Can anyone offer any documentation for yay or nay?
