Thanks all. It really highlights what a brilliant resource the online archive is. I for one am eternally grateful to everyone who made it happen and for the continued work digitising and adding new collections to the site.
My understanding of the cam angles is below, I've drawn it as if you are looking at the lever side of the backplates of each side. Hopefully shows that the lever is at the same angle to the centre line front and rear as dictated by having the same cam, and that the angle is mirrored about the centre line for the opposite side. Obviously the angles aren't exactly as they appear on the car, but hopefully it gives an idea of how the vertical front backplate and the angled rear backplate can both achieve the correct lever angle with same cam.
