Swiss manufacturer/custom painter AKU has launched a project aiming at the production of a series of eight Swiss Henschel shunter varieties based on the Hobbytrade model:

These cute machines in the liveries of the Feldschlösschen brewery, the contracting company Sersa and others are partly still in operation today. A total production number of 100 units will be required to make the project economically realistic. Accurate prices can not be given yet.

I will be happy to offer translation help if necessary.
