[Milsurplus] WESTON info wanted.

[J. Forster]

Is the face a slot with a bunch of reed ends? If so, there is a coil and
the AC field excites movement in the reeds. Each reed is like a one prong
tuning fork with high Q and only vibrates over a narrow range of
excitation frequencies. The voltage is likely 26 or 115 VAC, but that's a
guess.
