Chieftainmk4 Posted October 22, 2015 Author Share Posted October 22, 2015 The Enigma concluded. From the man who wrote about the Chertsey military proving ground, The Tank Factory ISBN 978-0-7509-6122-6. The model was a radar signature model one of a kind. The book was very informative capturing life and times of British military proving ground. Sadly now gone making way for a motion picture studio. From his own description. I believe it was built for developing radar systems. There is a one to one relationship between the model size and the radar frequency and so you could test a 1/5 scale model with a radar 5x the frequency and get equivalent results. There used to be an in-door radar range at a place called Hutton Moor near to Bristol where testing was done and being in doors with a scale model it was easier to control what was going on. This model is unusual because as far as I know it was the only model of its type that was motorised in order to look at the Doppler radar signature of a moving vehicle.

manny Posted November 25, 2015 Share Posted November 25, 2015 The Challenger with the man in the white coat is still around; not as big as the Chieftain by some way but still a substantial model. Power unit is gone but the transmission is still there. Suspension works and the track is made from individual links. The model at present weighs around thirty kgs. It looks like the elevation was controlled by a simple mechanism. All pictures taken today.[ATTACH=CONFIG]90766[/ATTACH][ATTACH=CONFIG]90767[/ATTACH][ATTACH=CONFIG]90768[/ATTACH][ATTACH=CONFIG]90769[/ATTACH][ATTACH=CONFIG]90770[/ATTACH] Is the challenger for sale? please PM me and name me a price if this is the case.
