More on The Avengers. Bet you couldn't wait! Two shots of a Mini Moke and one of a Stentofon, at least that's what I can see from the photo. Searching turns up newer models of these but none of this one. I thought it was one of those gismos that you see in this TV series but it looks real.
How did I know it was a Mini Moke? Well, that's what came into my mind when I saw it, don't know why, so I checked it on the Internet Movie Car Database. Works for TV shows, too.
