PDF instructions for building a model of an open-plan car, based on the type "m" as it was used very often by Deutsche Bahn. The middle part of the roof can be removed and reveals the inside. Inside there are 24 seats. Unfortunately, due to the construction, the doors cannot be opened. In addition to the chassis, other details, such as the transitions to other wagons, have been lovingly reproduced. The model is approx. 57 knobs long.
 This model fits perfectly to the model of the DB BR V200 .
