Another item to make a note of is the black handle shifter, shift gate is black, the bolts that hold the rear drive cover on are NOT cad. They are black and this is mistakes that are made during restorations. The sidecar bracket on the upper frame support is also black oxide. In the back ground are more military frames.

A 1936 BMW R12 on the assembly line with the worker putting the front end on the machine. Some very key items to note in this photo. First is the paint, a nice RAL 7021 Heeresgrau . Notice the flat appearance of the paint. You can see finger marks all over the fender and forks in this photo. The gas tank is 1 year only 1936 flip top. The tires are Englebert brand which is interesting as we have seen different ones on the motorcycles. (This photo is exclusive copy rights of BMW group Archive).

The military BMW R12 is a 1941 model. Notice the steel foot boards, black springs for the drivers seat, Military fenders and now you can see the saddle bag brackets on the rear of the motorcycle.

Some interesting notes to point out in the photo above.  First the same 3 motorcycles are in the photo. Its possible this is the opposite view of the same training room. What you have on the wall, the tools is incredible. Starting with motor tools directly in front of the view, than to the right is the rear drive tools. A interesting note is the BMW R71 with Berlin plates ( IIA). The motorcycles in this photo are a BMW R71, BMW R12 and a BMW R75. (This photo is exclusive copy rights of BMW group Archive).

Some items to mention in this photo. This is the only known photo of the warning label on the gas tank of the BMW R12. I have spoken to BMW Archives and they are unaware of any more photos of this warning at all. This is possible it was not used in the field? Some more items to point out are

  1. Black Oxide damper spring and top nut cover.
  2. Small rubber spacer for separating the control wires.
  3. Black oxide headlight bolts and not the washers.
