Period ad adds to the evidence
Re the ‘mystery sports car’, I would say it is an EB (Edwards Brothers) body on most likely a Ford chassis. Attached is a period ad from Car Mechanics April 1959 and although just an illustration, you can see the frontal treatment looks similar.
If the you go to the excellent website www.fordspecials.co.uk you can see some photos. Apparently the early bodies were sold as front and back sections without doors to allow fitment to chassis of differing wheelbases and in the picture accompanying Joey’s letter you can see the sill below the door is a separate section.
