I seem to recall I had a model of the Mk6 - it might well have been a slot car model - when a much much younger person. A delightful thing and the overall design - straight roof line from the top of the windscreen and the tail with the Mk1 Cortina lights seems to be echoed in the Howmet to some degree.
I had not realised that Eric Broadley made 3 Mk.6s
But we digress .....
