A guess is that this might be 250 cycles/rev, which is a bit low.

You might open it up and poke around carefully inside. Most
of the older units had discrete components on a PC board, and
you can figure out the power terminals because they will have
a polarized capacitor between those 2 terminals. Once you
know the correct power terminals, you can figure out the
rest with a DVM and turning the shaft.
