The Hornet was in service with Cyclops Sqn 2 RTR which was the Malkara trials unit. For this they became absorbed into 3 Div which was part of the Strategic Reserve.
So the markings are correct other than upside down 3 Div sign. That actually was bit of a sore point for me. This is not the vehicle I had, but when I restored 'mine' I carefully photoed all the markings & repainted them all closely following the photos so there were no errors. On the first show I met a chap who was actually a sign writer in 3 Div who reckoned he had painted several thousand such signs. He pointed out, very nicely, that my sign was upside down!
I had copied the photo, but had got the photo upside down as there were no reference points. The sign on the rear was ok as there was an edge for me to relate to. Dooh!
