Today I replaced the manifold on my 1929 Tudor with an Auto-Lite one (a little heat is wecome in WI). As I was cleaning the block around the ports I found a B stamped between the middle 2 ports, any idea what this is about?
Brent, Years ago, while waiting for our first Jaguar MK. 10 to arrive, the factory sales brochures arrived, showing a pic of the engine with the carbs on the L/H side!! I surmise that someone flipped the negative. Those brochures are probably a "collector's" item by now. Bill W.
