I just found another photo of the horizontal radiator Emeryson Mark 3.
Go to racebears.photodeck.com
Then look under 1960s & Formula Junior and there is a photo of the Mark 3 at Goodwood with unpainted aluminium bodywork with race number 19.
Despite the caption it is an F1 - carbs on the left being the giveaway.
A copy of that is here in my files. I came across it looking for other period stuff for my own preferred marque. JCJ raced it at Goodwood. The picture featured as one of the questions in the quiz which Glyn and I set for RTH's film show last summer. Something of a rare shot, and well worth having for Emerysonistas. As an aside I can recommend dealing with the Racebears sitre. Like Ted's products, the photos are well produced, well priced, and well packed.. Usual disclaimer.
