Had the aussie version parked at the entry to a base I worked at in a past life. Boss had the illusion the mechanics could get her going after sitting there for years. No luck as one could imagine, but I got a good look at it inside and in the engine bay. No complaints about about the nice easy auto trans in the Leopards that replaced em.

Old man used to transport em around in the 60s. Has a few good stories about dickheads that tried to sneak inside on the left at intersections - to transport one by road in those days it was truck, dolly, float and a push truck A framed to the back.
