It’s not original colour but colourised and a mix of a number of what I suppose are either IWM or British Pathé film sequences. The first Honey driving through the picture has CRUSADER markings, but then there are Shermans and dual-colour Crusaders, and a staged attack scene intended to show the capture of Gialo, as well as infantry in summer kit.

Still, easy on the eye.
