In my wanderings about the web, I came across this promotional film by the BL: Rover-Triumph Film Unit.
Made,I guess, in the early 1970's, on how to use your Series Land Rover, and how to drive it in 'cross country conditions.
A brilliant bit of British-ana, and VERY informative too, like how to use the red and yellow levers, wading plugs, when to lower tyre pressures and how to approach obstacles!
So, I have saved it for posterity and put it up here for you all to enjoy..........
Also quite useful to refer Series Newbie's to, when they ask the inevitable questions about the levers and stuff on the forums!
It's in two parts, because the original film is about twelve minutes long, and JUST too bit to put onto You-Tube in one go. Sorry!
