Hello Ralph,
I'm new to this site. My father was Mike Cooper-Slipper and the aircraft that you describe as the one you are/were building was indeed his Hurricane, L2012, UP-V. In 1986 my father and myself along with a friend, Steve Vizard visited the site where the Hurricane crashed some 46 years to the day after the event. Steve has been on many digs throughout his career and retrieved some bits of wreckage from the site near Marden and I am in proud possession of the engine tachometer housing form that Hurricane. My father took the photo you've referenced sometime before September 15/40 at Croydon and I have the original somewhere in my possession. Please be kind enough to keep me updated on the model you are building which in all likelihood has been completed by now.
All the best from Toronto
Kind regards
Chris Cooper-Slipper
