Thanks for the lock Gerd. After much internet research I have been unable to come up with either a photograph or any proper model designation. The following sentence contains all of the information that I have been able to glean regarding the Weise automobile.
The Weise automobile was a Dreiradwagen manufactured in Berlin in 1932 and/or 1933 (depending on the source), selling for RM 1,750, and powered by a single cylinder 200-cc Rinne 2-stroke engine that sat without cover over the single front wheel.
If this sentence does not contain the information you require you might as well unlock the puzzle, as I don't know where else to search.
