Early Carburettor

Can anyone help  with the markings / stamps on the top of the carbs neck ? I have found a set of carb's in my spare parts box ,they have the short slides and springs and brass horizontal vents . The making is 064A a square with a A filled by OC ?

I can't help you with that Rick but I can help relieve you of those carbs

A picture would help with identification. Are these just bodies, or a complete set on the mounting plate?
I seem to recall the early straight vent carbs on #302 are marked as B750A, and that on the mounting plate rather than on the actual carb bodies.
Curiously, later 750 F1's had carbs marked with 064A?
