(Someday I'll complete my set of Whitworth tools)
Complete them? You mean _all_ sizes? I am not sure what the smallest BSW
size it, but there's certainly a 1/8". There is also 5/32", well known to
every UK boy at one time -- it was the screw used in the Meccano sets.
At the top end, I've seen 1+1/2" BSW (used for the hub bearing nut on
some British rear axles), and I am pretty sure it goes well beyond that!
