Oh, and just to be picky, it was just plain "100". Although there
were the 100M (LeMans) and 100S (Sebring). When Healey brought out
the six cylinder model they called the 100-6, people started referring
to the old ones as 100-4s.

Like "flathead Ford" in a way. I don't think the "flathead" nickname
came about until the OHV engines became common in the early 1950s.
