Her Mag was officially a Driver/Mechanic with the Her Dad's Corps of Transport, and a zillion years ago she popped out to say hello to a couple of us who had parked our Series I and a IIA on the side of the road for a brew up, when she turned up in a SIII, and stopped for a chat ... about Landies!
Courser, being peasants, we hasd no idea who that dear little middle-aged, knowledgable lady was until someone in a suit approached and asked if everything was OK and that Her Magesty sends her thanks and regards for the chat, alondg with her apologies for not accepting a brew!
When we got further along the road we saw a sign for 'Windsor', and even then we didn't really twig!
