@Eric: it took some time to search…and actually none of my sources is
definte…only at time it was quite normal you had the changes done
locally. Here two examples from DO 2000’s
DAFX: Tractor with sleeper made by MEDEMA from Appingedam, whereas
the trailer is from DAM also from Appingedam. Model is from 1958-1958
as also the temp-registration indicates.
DAFY: Drawbar with sleeper (sort of semi-top) made by Paul & Van Weelde
from Nieuwerkerk a/d IJssel and this model is from 1964-1965.
The two DO 2000’s you speak about might for example been outsourced by
the DAF-dealer to Roset, P&VW, Koster etc.
I will check further
