F. W. Evans used to be my LBS in '94 when I was stationed in London - I lived in Kennington my first year there. I know by then they were not building the frames there, but they were still using the exact artwork your frame has - and they also still used the old lamp bracket on the odd frame here and there, too! In fact, nearly every Evans frame in the showroom was built with touring in mind.
I ended up switching allegiances to Condor Cycles at Grays Inn Road, partly because I'd moved away from Kennington but mainly because one of Evans' mechanics broke the cable anchor off my Campy 50th Anniversary rear derailleur.
A year later, I was finally recompensed after they had exhausted their search for a replacement (in that time I found two complete sets and bought them both - I wish I had them today!)
