[Amps] Motorized Jennings Vacuum Cap

[w3kl at w3kl.com]

I have two old motorized Jennings vacuum capacitor units that I need schematics for.  I don't remember where I picked these up - swap meet I think.
 
The units look like they were removed from a tuning system of some type - not necessarily for radio though. Perhaps a medical device (MRI etc.).
 
I can send you photos of the units if you like.
 
The system has a 26.5V DC motor made by Collins. The motor drives a speed reduction gear system that then drives a pinion gear that moves a lever that pulls the capacitor plunger in and out.  There are two limit switches on the unit.
 
The interface to the unit is via DB 25 connectors.
 
I can sit down and reverse engineer the wiring of the unit but I thought I would see if someone already has a schematic for it.
 
I intend to use them to shunt feed my tower on 160.
 
Thanks for your help.
