Well 55 and 23 had the same cab body. 55 is a lot bigger and had 10 wheel nuts,.This is a 23 since 1953 they had this body, technically it didn't change much. For size see the mercedes next to it.
Thanks for the lincense plate info. We did only see the AFC cars around here in the region. The Afcent base is 8 kms from here. The base vehicles were used very locally i think. Later as they opened the militairy vehicle depot here in town we did see a lot of american trucks and MP vehicles but they all had US-plates.
