It is curious, I have a photo of a Zis 14, but I had not realised that the 12 and 14 were, to all intents and purposes, the same truck.
Thanks again for widening my knowledge, also thanks to Luftflotte2 for the extra information.
Hi again Kerry,
In hope this list of LWB ZiS trucks will spare you some headaches in the future:
1. ZiS-11 - chassis for fire trucks with PTO;
2. ZiS-12 - basic chassis;
3. ZiS-14 - same as ZiS-11 for military use;
4. ZiS-8 - bus chassis, same as ZiS-12.
All they are with 4420 mm wheelbase.
