Is the peace sign a doves foot?

I thought it was, but I read this today:

The symbol is a combination of the semaphore signals for the letters "N" and "D," standing for "nuclear disarmament".

In semaphore the letter "N" is formed by a person holding two flags in an upside-down "V," and the letter "D" is formed by holding one flag pointed straight up and the other pointed straight down. Superimposing these two signs forms the shape of the centre of the peace symbol.

The original drawing by Gerald Holtom of the CND symbol is housed in the Peace Museum in Bradford, England. ~
