Daniel has mentioned and shown JEP Mignon before. This week I also acquired a JEP Mignon set. This set is from 1926 and is complete or maybe even more then that, since the books do not mention a set with 4 cars like mine has. JEP Mignon runs on 5/8 Inch track which is just a bit smaller then H0 gauge. The locomotives runs but the controller is not working (but would anyway be unsafe to use). The controller lamp seems to be OK.
The set includes a station and some accessories.
