Hello Andrew, thanks for those measurements, and I think you are right about the CAV 8".
I've only some scale model kits to base measurements on, but estimating the front box as being 68 inches wide, and taking the following photo (rotated a bit to easier measure horizontally):
Scaling the photo to match the box width, the headlamp measures out to almost 8.5 inches. If the light frame is a 1/4 inch thick all around , that leaves 8 inches for the lens, if that is how they are actually measured?

Hi Bruce, thank you for the historical connection. Dingos used for training were of the earlier mark based on the photos showing a revised headlight arrangement from the Mk IB to Mk II. Yes, Hector serialed
