I have "found" three more 975's on the web.
One restored by "Cameron restorations" in the UK and oddly enough described as being a 970A, but the data plate shows it's true identity. (picture 1 &2)
This truck seems to have the same rear body as the ex-Howard Wade 975, which I presume is a body fitted post-war by the Norwegians or Danish army(?)

The other two are in the "Piana Delle Orme" museum in Italy and retain their Original bodies. (picture 3 & 4; Second Diamond can be seen in the background)
