Thanks Kevin. I won't be adding any more wear and tear to the Spit MkVIII, as it was only a couple of months old at the time depicted.(And they were freshly re-painted in the dark earth upon arrival in India).
The main thing was to get the dusty, dirty look right, comparing it to the film footage taken at the time.
Still working on the base at the moment, plodding on making two or three young Acacia trees, and some scrub etc. I should have some pics of the progress sometime over the weekend - I hope !
