Nice pictures Gert! How common are Mack trucks in the Netherlands? Do you know how old these are? Think I have read somewhere that the R-series originates in the mid sixties?
In the 60`s and 70`s a lot of Macks were sold, now there are only a few who still use them and a lot restored trucks, i`m not sure but i also think that the R-models are dated in the 60`s.
