That's an interesting photo, Reid Railton, and it shows some significantly curved main tubes in the space frame, something I though only the Coopers did.
I hope that photo has been reversed as the WA has its inlet/exhaust on the offside. If, as I think, that's the steering column passing in front of the engine it is wrong for a r.h.d. car and evidence of reversal. If it can be shown not to be reversed we have another problem . . .
