I've got some black & white and colour photos of a couple of these cranes running round the yard, plus some 8mm cine of them too. I'll try and post some of the photos soon, but the cine film is trickier!
As soon as I've figured out hoe to upload them, I'll post a couple of photos of the interior of the pool which I took when I worked there during the summer of 1976 (I think)
