I think the one in the first picture might be Simons truck in a previous life (?).....here it is at Wings and Wheels in Belgium in 2015. It has to be the D15 that was restored by the late Johan van Rijn.
second pic shows a D15 in Normandy in 2009.....I though it was owned by an Italian member.....but looking at the licence plate it might be British (?).
Last picture shows a Dutch D15 in 2016
