Just checked my spare, if you have a TR3/4 it is on the top when  
viewed on the engine. It reads:
LUCAS
22700 0 12V  [preceded by a graphic that looks like a Y in a circle]
C40 46 70
[an arrow for direction of rotation]
Made In England

So this is now on my Spring to do list; to swap it for the one in the  
car which is the older version.
