I'm building the Tamiya Challenger 1 model at the mo I've got the etched bits and the excellent conversion from the firm Castoff which has the correct coffin bin for the mark 3 as well as the baskets full of kit. When I was in we never painted the butterfly. This is the towing adaptor fitted to all tanks which was left in it's gold colour, did/does everyone do this? The Mk 3 I got back (in 1991) from the first Iraq war never had the extended external tanks was it a Mk 3 (it had the dozer hole on the front which I used an acid test) when were they adpoted in BAOR? In the 80's on test we tried an antenna with a white ball n top fitted the gun crutch bracket to help the commander when reversing closed down, did this ever take off?
