Need help identifying windscreen wiper system

[John C.]

We are in the process of gathering some of the last items needed to finish the restoration of 43GX, a 1931 Rolls-Royce Phantom II Continental with body by A. Van den Plas et fils of Brussels, Belgium.

 

One of those items is the windscreen wiper system as shown in the photo below.  The motor appears to be mounted to the rear by two bolts on the left side of the bottom base trim around the glass, with the main wiper and a slave being driven on the front, likely necessitating as many as three holes through the glass.

 

We think it’s probably of European origin and are hoping to identify and find a system to acquire.

Looks like a Bosch to me.  The holes-in-the-glass was used on some Steyrs and others in the 1930's.    Here is a link to some photos with a Steyr with the same wiper system:  

I posted a photo of a restored Steyr Type 55 that is missing its wipers, but has the holes in the windshield here: https://forum.studebakerdriversclub.com/forum/your-studebaker-forum/stove-huggers-the-non-studebaker-forum/110253-portland-art-museum?107731-Portland-Art-Museum=
