The older BSA's used the Amal Monoblock. They later
progressed to the
Concentric.


Ain't Google wonderful?



If you can find that information using google, please post a link so
others can learn something that I already knew from experience.

Maybe you can also find a link to a website explaining how SAE and
Metric wrenchs are "just fine" for use on Whitworth fasteners.

Whitworth, is a thread standard, it defines the shape of the
thread,(thread form). It is not metric. The standard also defines the
size and shape of bolt heads and nut forms, it is not metric either. The
head sizes do not conform to normal SAE tools or Metric tools in some
cases. Most mechanics refer to these as BSW (British Standard
Whitworth) and BSF (British Standard Fine), the do not call them
"Whitworth" wrenches.
