Another from Germany

This is another kit Martin found that has similarities to the Machine Shop. It's Vollmer kit # 45612, called the Workshop.

Frankly, its look doesn't say Workshop to me. It says things like bank, library, accountancy, or post office. Removing the peaked ends to convert it to a flat roofed building, and getting rid of the roof-top stuff as well as the decorative insignias, it could reside on the OPL. 

These Machine Shop like buildings are no doubt a common building type in the world of HO architecture.
