Cyclamin, I have 1 x Cyclamen HJ Sandman recorded, it is a 10/75 Elizabeth van, 253 4spd with black trim. So the one you had can't be the only one.

Taily, I didn't look all that hard at the BODY plate, and you are right, they did very well to get this clean. Dandenong BODY plates went on prior to the whole paint process as a Dandenong vehicle used the BODY number to track and assemble the car. The black baked on dip and electrostaticaly attached red oxide are almost impossible to remove. They must have used acid or paint stripper on it. You'll notice a little subtle change in how this plate is attached on original vehicles circa 1975-6 which is not well known and brings a few people unstuck who remove them and claim they have never been touched.
