Certainly the pistons carry the same Hepolite RS7665 number and size specifications, Tony. Perhaps the 1939 New Eight had the same 'Big 7' engine with the post war Eights having a slightly different engine? The catalogue isn't clear on that point, merely saying the RS7665 pistons were fitted to the 1937 to 1948 'Big Seven' 8hp 900cc and the 'New Eight' CR 6.8 to 1.
