Can you identify this vehicle?
Brütsch Einman Auto also known as Monposto or Eremit and also mentioned as model S or T depending of the source, typical mist-up of Brüstch model names. It's from 1950.
Absolutely correct. It's the 1950 prototype with a NSU 125 engine operating on just one rear wheel. The body was realized by Wendler. Another quick point for you.
