This video focuses on Lord Mountbatten and a visit to see troops (in India or Burma?).  there are several clips of him traveling by jeep.

This closeup of the windshield appears at the 1:23 Mark.

“A jeep drives across bridge and into an army camp. Lord Louis Mountbatten inspecting troops lined up in the open – British and Indian, some black men seen. Lord Mountbatten addressing the gathered troops. Various shots of Lord Mountbatten walking around the camp talking to the men. A man on stretcher is carried towards a plane.”
