I believe I found the car that you requested more information on,it was called the Scrimp, or nicknamed as such,was built by Wilkinson Automotive Developments in Hertfordshire in 1965-66.It was commissioned by Alan Fraser,he apparently had commissioned several prototypes at the time,his chosen car was designed by Tom Killeen.Mr. Wilkinson had a small number of staff working for him at the time.The car was delivered to Mr. Fraser as a non runner. the information I have mentions that one of his engine people made the engine to run backwards,as the Imp engine and the box was reversed in the car (mid engine instead of rear engine),the car had a steel monocoque chassis with aluminum panels.The wheels were Hillman imp,the rear lights were Hillman hunter. The car was done in british racing green.,also the car apparently never had an official name,but nicknamed Scrimp.
