In the sdkfz topic you mentioned possible ip issues, could you go with the vehicle name and type without the manufactor?
The 3t 2*4 were named by the cylinder capacity, the wheelbase and mode of drive:
so you could nsme it Blitz 3,5-36 S (early version 3.6l. 68hp motor, 3.6m fromt front to rear axis, Standard rwd) or more more common version Blitz 3,6-36 S (with a 75hp motor)
