1925 Dodge Brothers wiper motor

[FMF]

I'm looking for information on a vacuum windshield wiper motor for a 1925 Dodge Brothers 2 door coach. This motor mounts outside the car directly in front of the driver and is housed entirely outside the car.

I am trying to identify exactly what the motor looked like in order to attempt to locate a replacement. I would appreciate any information you might have. I can't even locate a photograph/model # of this motor. Ironically, it is the only part missing on the car --- I even have it's mounting bracket. The mounting holes on the bracket for the motor are 5 1/2" apart.

I would appreciate any information you might be able to offer.

Thanks and Best Regards!
