It is my understanding that the standard pitch of "A" at 440 Hz was
established about 1930, and that before that many different values
were in use.  At DeBence we have been "guessing" what values to use
on various machines.  That sometimes has turned out poorly.

Does anyone have a good listing of which companies used what tuning
pitch on their nickelodeons and band organs?
