Another dabble on ebay, another bike of dubious provenance. I'd be grateful for any help at all in working out what this is. The bb shell is stamped Nervex, cranks are Williams, bb is Bayliss-Wiley, handlebars are GB Maes, but a different version to the one I'm familiar with, with a frilly edged collar to give th correct diameter for the stem to clamp on. The internal diameter of the seat tube is 27mm, measured with my slightly suspect adjustable wrench. There are no holes for a head badge. The head and seat tube angles are not parallel; some (but not all) of this is due to a front end shunt...
