Yeah, I recall hearing the same thing about the Whitworth wrench size
being the bolt shank diameter.
One further comment: I called the local Snap-On warehouse to find out
if they carried Whitworth wrenches. I was told by one of their counter
people that they didn't but that they did carry British Standard
wrenches which he claimed had the same dimensions but were sized
differently. He said that the BS (no pun intended) marking was about
twice the size of the W marking. I assumed that the sizes marked on
these wrenches were the actual wrench openings.
The place I ended up buying the 1/4 W wrench had one in stock so I
was able to confirm that it was the correct size on the spot.
