Asking price for complete collection is 4000 which is around 1000 less than the total value sold individually.

I haven't tried to write a history of Watkins/WEM because there is such a good site on the subject that I couldn't compete with or indeed want to. If you visit the link below there is just about everything you want to know and a link to an archive to a video of Charlie Watkins explaining how he invented the copycat and showing the first one he made. Brilliant.
