Hi, after flicking through the lists of Trade posts (up to 200), but could find no one mentioning Exeter, so here goes!!! Know about Exeter Flying Post newspaper, from around 1750's, and of course there is the Gentleman's Magazine, (ok not based in Devon but does have some info in it!)
So it seems there is no book of Exeter with lists of Tradesmen, up to the 1830's or am I wrong???
