Don't have any photos sadly, although I still have the drawings. It was basically a steel cage (err... I mean `elephant handling device' ... Zoos don't like to use the word `cage' any more) with sliding gates at each end and movable sides to `crush' the elephant, plus lots of inspection ports to allow the keepers and vets to take samples, administer injections, etc. It also had an overhead gantry and winch so they could lift any elephant that might collapse. It was designed for a 6.5 tonne Asian elephant as we don't have any African elephants here. The keepers rate elephants as the most dangerous animal in the zoo - particularly the bulls when they're charged with testosterone. Very powerful, smart, and they remember people they don't like. If they pee on you, you're OK. That means they like you.
