Perhaps I'll have a go while there are a couple left.
I think Matador 02, the elevator truck, would have been built in about 1951 by Ruthmann of Gescher, Westphalia.
And I think this links with Match 03, which is a Ruthmann Steiger TU700 hydraulic boom truck set up for fire-fighting, and specially designed and built for the city of Rostov am Don, in Russia.
