If the motor is a stepping unit, it is a WOMLY/Antenna Mart switch.
I'm sure Alan Bond at MGS could provide documentation in that case.
Try: info at mgs4u.com.
If it is not a stepping (ratchet) motor, you probably have the
outdoor half of a Drake RCS-4.
The W0MLY/Antenna Mart switches were housed in small Hoffman type
boxes while the Drake switches were in anodized sheet metal
