Hi, are you interested in this vacuum motor?

the power window motor is nothing like a windshield wiper motor.  Trico developed a vaccuum based lindow lift system for cars that became available after World War II and used in the 1949-50 Kaiser Virginians and 1951 Frazer Manhattan hardtops.  Servicing information was not in the 1949-50 and 1951 shop manuals; Kaiser-Frazer issued servicing instructions as a separate service bulletin in 1949 that features a phantom drawing showing routing of the vaccuum lines, lift motors, etc. 

The system is different from the hydraulic (fluid) power window and power top systems used in Buicks, Packards and other makes of higher end automobiles.  Both systems fell by the boards when 12 volt ignition systems came on line.  The higher voltage produced more electric current (amps) that made powering the window and (as applicable) top systems easier on the electrical system.

I'm looking for the window motors. They are different for each location, left front, right front, left rear, right rear are all different. Every once in a while I get one on E Bay. I bought one a few years ago, and I just bought 2 right rear motors on E Bay. Usually the seller has no idea what they are selling. I needed some good diaphragms for my motors, and was looking for rebuildable units. Being 60 to 70 year old units, even the new ones are not useable unless they are rebuilt. When the motors are working properly, the windows zip up and down quietly and quickly. The speed can be adjusted by the solenoid valves on each end. I set mine to the quickest setting. The inch before full close, the window will slow down and close gently. There is a plunger in the window motor that purposely does this to keep the window from slamming shut. It's the coolest thing to see.

Just curious....do you have them in a Kaiser Virginian or a 1949 Frazer Manhattan sedan?  Some factory materials hint that the Manhattan 4-door sedan could be ordered with the window lifts and that a handful might have been turned out that way.

They are in my 1951 Frazer Manhattan 4 door hardtop. Factory installed.
