Strange terminology.  "Piezo" (pronounced "pee-AY'zoe") would be either 
crystal or ceramic (or similar pressure/electrical sensitive material;  
today we have piezoelectric plastic, etc.); "dynamic" is always used in 
microphone nomenclature to indicate a moving coil in a magnetic field.

Is the brand name "Piezo"??  Or maybe it has dual elements?  (Kind of 
unlikely, especially in the 50's)

A lot of the older microphones are very midrangey, with poor bass 
response and treble response.  Terrible for voice and hi fi, but exactly 
what many like in the way of harmonica amplification.
