Froggy55:
Couldn’t it as well be a recabbed Mercedes LP? Its wheels match with the ones of the LP 333 of previous picture.
It is an LP- possibly a 315. Those came as “standard” with a Wackenhut cab, from 1955. They were the first “production” European forward-control heavy trucks. I put the words in quotes, because the LP was also available with Kaessbohrer and another coachbuilder’s cabs. The name of that other metal-basher is in my other computer, and I am not at home 
.
The cab on the drawbar outfit in the picture does not look like any of those. Indeed, it looks like a Buessing, as suggested. I wonder if it is by that manufacturer’s similarly-named supplier, Buessing und Sohn?
Whatever, it looks like a very comfortable vehicle in which to travel around the sparsely-trafficked 1950s European roads.
