I bought a set of Whitworth tools from Snap-on years ago when I was attempting to restore a Bentley (automobile). If memory serves, they were call "British Standard" sizing. You might try this link:

Snapon is still available. Craftsman used to make them but don't think they are currently available. Might try Mac tools. Ebay is a good source also.
