Hello Jim,

I have seen one of these telephone crank generators. My friend Chuck Cook has 
one. One day he showed it to me, and I attempted to slowly turn the crank 
with my hand on the electrodes. Man oh man was that foolish, because that 
sucker gave me quite a wallop! Anyhow, we measured the voltage while turning 
as fast as we could, and we got the thing up to 500 VDC. That's I know about 
them.

                                                 Good Luck, Richard Harris
