I posted recently about my Vanguard. I didn't mention that my Solex carb
is probably Whitworth as are the SU parts on my other LBCs.
You mentioned Aston Martin as probably using Whitworth. Most LBCs prior to
the sixties used Whitworth fasteners - except Standard-Triumph. My '57
Lagonda is all Whitworth. My Austin A40 was and I suspect my Jaguar is but
I haven't looked recently.
