1930s Mercedes-Benz spiral bevel gear set

I'm replicating this allegedly original gear set and find it very interesting that it was made with the Gleason system, while I expected it to be made with the German Klingelnberg-Palloid system, which was already available at that time. Does anybody know more about the technology they used there?

100% guesses follow.

Today Klingelnberg generically are predicted to be more expensive.

It may also be that K focused ( or was forced to focus ) on industrial applications in those early days.

Or perhaps the inherently slower K process precluded competitiveness in production applications where a set of well designed lapped Gleason gears was plenty strong and acceptably quiet.

According to

https://en.wikipedia.org/wiki/List_of_Mercedes-Benz_vehicles#1930s

, the annual production volumes at that time were in thousands and not millions, so productivity was probably not an issue. Maybe they were simply buying the spiral bevel gears instead of making them?
