[TowerTalk] Identify Remote Rotary Antenna Switch

One of the things I picked up at a recent hamfest is the remote head
for a rotary antenna switch. The switch is nearly 6" square, although
one side is only 4". It has 6 SO-239 connectors and a terminal strip
with 8 terminals.
Opening it up, it has a conventional ceramic wafer switch switching
the SO-239s, an additional phenolic wafer that attaches back to the
terminal strip. The rotary switch is driven by what looks like a
phonograph or clock motor through a geared reduction.
I'm guessing this unit takes 25-30 vac to run the motor, which then
stops when the correct detent is chosen. As I don't have the control
head, I'd appreciate any information on this type of switch. I figure
I can build a control box pretty easily with the right info.
