There is a recent episode of PBS's series "Secrets of the Dead"
which says that many things credited to Leonardo aren't actual
from him.  As well as I understand, he had drawings of lots of
things that he didn't invent, and others later gave him credit
for them, even though he didn't claim the credit. 

I am not sure this is one, though.
