But while I was idling my time away our club historian (Brian) dropped me an email to tell me that 70 DNR appeared in 'The Filby Files' book on Classic Kit Cars. I was worried when I heard that, never having thought of it as a kit car (which it never was!), but I picked a copy off ebay a couple of weeks later and found it littered with lots of things like TVR's and even Lotus 7's.
And there, squeezed between Gilbern GT and Gilbern Genie was a picture of my car in earlier days. So the editor had clearly struggled a bit with his alphabet as well as his definitions. Although, to his credit he recognised the car as an 'underrated and quite Collectable sports GT car'.
