I don't know of a list of shows anywhere, appart from rather sketchy ones in magazines' "diaries". The main one in Devon is, of course, Axminster's Tools 2003 which is at the Westpoint Exhibition Centre in Exeter. 6th-8th November, I believe. Much closer is Yandles (Martock, Somerset) spring show on the 11th-12th April. Other than that I don't know, but if you find any more let me know. I may just venture over the border!
