Just go down to your Sears store - they have them right there in the
store, don't even need to do a catalog order. At least they did in '59
or '60 when I bought a '53 MG-TD and needed Whitworth wrenches for it.

More amazing is that the Sears store was in Youngstown, Ohio - the home
of maybe 2 MG's. Wait, maybe that was a Pittsburgh Sears. But even
Pittsburgh didn't have enough English cars to justify Sears carrying
those wrenches. Not just a couple of sets, either: individual sockets,
box ends, etc.

Sears' good old days.
