Scania Vabis LV type

The green cab is most certainly a Hoogeven cab. Also circumstantial, but many strangs of evidence lead to it. Carrosserie Hoegeeven was a subsidiary of Motorkracht, the main importer for Magirus in Holland, but not just Magirus, also International and others. Motorkracht was alo responsible for exporting Magirus to Belgium, not Ulm, Germany. Motorkracht got the parts from Ulm and then build the vehicles from those parts. But they also made their own parts, the Belgium models, for instance, had plastic doors.
Keeping all that in mind, have a look at this Magirus:

Lot is in Belgium, so it probably has been imported by Motorkracht. You couldn’t get a cab like that in Germany anyway, so it’s most likely built in Hoogeven.

Evidence B:

That logo on the door is for GTW (Gelderse Tramwegen), a general public tranport company that ran also a lot of buses. Most GTW vehicles were Magirus and half of their buses had Hoogeven bodies… It would make sense, if they wanted a Scania and it would be available via Motorkracht, they would source it there.

Evidence C:

This is clearly a motor show, and also it is in Germany. It reads something with “in Stunden” on the rear cab, but also the 16,0t Stickers are clearly German. Which means these Dutch Scanias with Magirus parts have been officially imported to Germany by someone. In can only think of Motorkracht.

Another show, the sticker in the window says “Lack” I think, so it might be in Germany again. Next to it sits a Magirus. So the Magirus connection is definately there. It wasn’t just someone buying glass from Magirus, there is a real connection. The obvious Dutch Magirus connection is Motorkracht. Motorkracht was the owner of Carrosserie Hoogeven, and would use their services, if they were to export any Scanias to Germany.
