Elin Sports built by Graeme Amos, NZ
Yes, this is one of several Amos cars that are referred to as 'Elin'. It's difficult to distinguish between them--not only because he reused the same chassis for two or three Elin versions, but also because even the people who knew Amos and raced with him contradict each other when it comes to the details about his cars.
For the point, all I'm asking is that you identify the brand of the donor car. I have the entry list from the event where this photo was taken and the car is identified as "______ Sports," with the blank space being the donor brand.
LOCKED for you.
