Jim,
just because a dealer handles two lines it does not make it the same manufacturer.
Cosa US had Weiler and Ravensburg at the same time.
Cosa Canada had the Whacheon lathe labeled COSA (when we were forced to import machine through our Korean sister company) and the Weiler, as well as Okuma & Howa at the same time.
Canada also had to import a certain dollar value from Taiwan and had the Lillian turret mills labeled COSA, but that did not mean that Lillian or Deckel owned each other.
Before the dates and model numbers given by me above, ONLY "E" and "V" MODELS were VDF machines. All other models by the different manufacturer were "House Lines", NOT, stress NOT VDF machines.
VDF was NOT selling machine in Germany. Each constituent company had their own distributors.
The VDF Division managers of McDougall lathes, a wholly owned subsidiary of the Canadian dealer Upton, Bradeen & James, came all from Boehringer and thus pushed in their competitive sizes the Boehringer house lines over the others in the group.
Really cheesed me off when I saw perfect HHH S500 applications at customers but the management pushed the GBG 44S model.
UBJ today is a wholly owned subsidiary of Boehringer in Germany, which in turns is a daughter of Industrie Werke Karlsruhe. IWK owned Schaerer and closed it down and owned SHW (Don's beloved Deckel FP6 & FP7) and closed it down.
Upton, Bradeen & James was founded in the early 50's by the Canadian managers of Fairbanks-Morse, Rudell Industrial Division, who were the agents for VDF in North America.
The ultimate joke for me today is that since last Fall, UBJ is the Romi importer.
When I left the service at UBJ to take an Order Clerk job at Cosa they took me to the show room and I almost walked out.
Here I was servicing and making main assembly of the "best lathes in the world" (by our own admission) and now was going to work for an outfit that handled lathes that looked as if they came over with the Arc (think of the looks of a Herbert 4D Senior pre-optive).
"The D and L series look quite a bit like H&H machines, but the catalog says Wohlenberg."
I would appreciate a scan of the page with the model designation and data.
Ravensburg
When Cosa US took on the distributorship for North America we became the Canadian agents by default.
None was ever sold during my time there I know of two large roll lathes sold somewhere in northern Quebec in the 90's.
Ravensburg became a subsidiary of Heyligenstaedt in 1998

and is alive and kicking.
Seeing your note on light duty lathes.
In the spring of 1967 3 new Wohlenberg V800 were delivered to Jerry Hydraulics, Div. of Abex Industries in Waterloo, ON.
We went in and after leveling removed the head stock and tail stock and scraped in 14" (fourteen) raiser blocks.
These machines were bought strictly for the machining of the swivel joint of the F111 wings.
Actual machining was relatively light duty but the single piece forging of the shaft (tube) and arm needed that swing. By starting with the Wohlenberg they still ended up with a very strong machine that could deliver the proper surface speeds.
I don't know what happened at Wohlenberg but before the lathe division was sold off AML in Chicago had bought the plant for the paper equipment.

Well, another epistle for the Biography shoe box.
