Re: [AMC-list] I had to send it (Whitworth sockets)

["Armand Eshleman" <aje1@xxxxxxxxxxxxxxx>]

When I was a kid back in the 70s we used to joke about a
fastener being whitworth when we couldn't seem to find the
correct size wrench to fit things. We rode British motorcycles.
We also cursed Lucas electrics, right along with whitworth...........
same category of quality and mentality of engineering..........
So wonder no longer, some of us did actually know the difference back
then......
