I found a very cryptic description of this car that included the attached photo. It describes the car as "Edgar Salwegster's Lotus 7 Replica," Well, it ain't that. However, the same site has another photo of the same car that's named "R Gray- Everson Eagle 2". I assume R Gray is the car's owner.
Another site also lists it as an Everson Eagle.
So...Everson Eagle 2?
