Hello from Lyon,
On the inside part of the top of the boxes containing the DISTLER three-phase electric toys-trains of the types 0B0 or 2B2, it is written :" DEUTSCHE PATENTE - GM - INTER PAT PEND" : is someone of the readers would have an idea on the filing date of the patent and perhaps its references ?
Best regards,
Maurice
