Marked as "Made in U.S. Zone Germany", it can be easily determined as made between 1951, the start of the production and 1964.
It is a Limo in red livery. I am not entirely sure about the paint; it could be the original paint that is crazing or it could be have been repainted at some point in the past.
However, it looks like it was never opened so it could very well be the original paint but let's assume it's repainted to avoid disillusions.
The mechanics function well but it could do with a little cleaning and oiling.
