Thanks Tony,
Yes I am that Steve M, I love tracked cargo carriers of all sorts. I'm not expecting vast reams of info on the tracked truck, just nice to see it was mentioned. I have Mike Cecil's book and a few photos from the AWM website and am considering ordering the film footage of testing. I spent about three hours measuring up and photographing the tracked truck when I was last at the museum... and I still missed a few things. Luckily I've managed to synthesise a number of dimensions from my photos.
I've passed on Nigel's book site to the powers-that-be... I'm pretty confident my Chrissie prez' isn't going to be a pair of socks
Steve.
