Need info on Whitworth hardware

[computerworks]

Can anyone help with some good web resources about Whitworth hardware?
I need a fast-track education. /ubbthreads/images/graemlins/blush.gif
I am interested in specs, patterns, sizes, threads, etc.
During what time-span were they used? (...if that is a fair question).
Were they used throughout the car's chassis? ..or in just certain applications. (...generally speaking)
...what went where?
Why was BSW used?

Any and all tutoring is welcomed and appreciated

Also - note that one of the BCF (British Car Forum) advertisers - British Tools and Fasteners - offers Whitworth fasteners and tools. You can get to their web site by clicking their banner when it shows up at the top of the screen.
