Frame looks nice, but you're going to want to at least change the wheels to something with aluminium rims (£100-200), and you'll probably want more than 5 gears for touring (£100-200 for cassette, shifter, cables, chain, chainset etc). Also, it's a typically undetailed ad for a 40 year old bike - if the headset, stem, b/b, and/or seatpost are seized it could turn out to be a write-off.
Bearing all the above in mind, I wouldn't bid more than £100, but that's me. I hate shitheap old bikes; I'd change everything except the frame and possibly fork...
