LBW Demonstration Kit

[nompere]

I have just found Patent GB2282543 filed on 12apr95 by John Byron Brnmor Williams GU24 9QQ for some adjustable telescopic arms for demonstrating LBW to umpires (and other purposes).

This seems to be a fascinating development of the original string idea by Leslie Cheeseman and (was it Derek Woolcott?) in late 1960 or early 1970 subsequently adopted by several ACU&S Instructors (Shuttleworth, Baskeyfield, McColl and others)

Does anyone know any more about JBB Williams?

Unfortunately, the patent seems to have ceased in October 2003. www.patent.gov.uk/patent/p-journal/p-pdj/2004-6001.pdf
