Hi Mathias,
every time I see it again I enjoy your amazing dio,
only the work you did on those old figures is commendable,
only note,
premise,
starting from my low modeling skills and my historical knowledge i would never allow myself to criticize the work of modelers much better than me,
but the BMW R75 was only available to the German army from the end of 1942, it would have been better to use a BMW R12 for example,
however nothing could change the opinion of your splendid work.
A greeting

From my album.
In 1941 the production of civilian motorcycles was stopped. Germany was at war and production was adjusted to the needs of the Wehrmacht. BMW motorcycles have always been popular with authorities - and thus also with the military. Single-cylinder models were used as light courier and training machines, and the R 12 was delivered to the Wehrmacht as a side car.
However, the war policy of the Germans required a motorcycle Side car that could be safely mastered on any surface - mud, ice, gravel, desert sand - and that required only little maintenance even at extreme temperatures and heavy loads. In addition, the motorcycle should also be able to cope with longer distances at low marching speeds without any problems.
No German motorcycle manufacturer had such a machine in their range, which is why a special development order was placed with BMW and Zündapp. In the winter of 1938, BMW began work on this project based on the R 71 engine. The beams of the bolted tubular frame were divided. This enabled the engine to be installed and removed quickly, as the lower frame part could simply be folded away. A rear wheel suspension was omitted for better stability. But while the frame proved itself during the test drives, there were thermal problems with the side-controlled motor in off-road use and on longer trips at walking speed. So BMW developed a new engine.
The result was a 750 cc unit with an output of 26 hp at 4000 rpm. The engine developed an enormous torque and, since it had a very low compression ratio of 5.8:1, it could also easily tolerate poor-quality or synthetically produced fuel. In contrast to the R 71 engine, no heat problems occurred during testing, so that the R 75 could go into series production in 1941.

And

Series production of the R 75 begins
date from07.1941.
Description
In July 1941, the first R 75 sidecars rolled off the assembly line in Munich. However, after production was relocated from Munich to Eisenach in June/July 1942, the majority of the R 75 was manufactured in Thuringia. The R 75, with seven forward and two reverse gears and a powered sidecar, was specially developed and produced for the German Wehrmacht.
