To Alex’s comment about the TSR, the APB section is also devoid of content.
Short of the chapter in Tony Hadlend’s Spaceframe book (which was published 18 years ago) there is really not much about them out there. I have never seen a picture of ‘my’ APB (a post Land Rover, 531 framed ’3×7′) and there is sparse detail about any of them out there.
Perhaps if Moulton/Pashley would give out details of the numbers made, in what colours and some of the specs of the old models it would be a great source of info.
