There's a few tell-tale signs on here to confirm its mine.
1 - The name-transfer set. This is in fact not the usual set of Bryan's transfers. It is in fact two-sets as I specifically wanted the name running up the seat tube the same as it was on the down-tube. Bryan's usual set was a 'stacked' vertical one. Bryan agreed because it would look better in pictures (highly likely given the competition level I was at) but 'moaned' about wasting another transfer set of unused elements. Hence, I know he wouldn't have done this lightly for others !
2 - I remember changing the BB unit and axle to a 'Miche' as we couldn't get a-hold of a Campag one once and this picture has a 'Miche' BB installed. They were not a common BB but were compatible with both Shimano and Campag back then at a fraction of the cost.
3 - Originally, a Campag head-set was fitted and like the BB unit was changed when it crapped-out and I got a cheaper alloy set. For the life of me I can't recall the name of it but if it is stamped on the head-set, I could confirm yes or no.
4 - The geometry looks odd and mine was odd. I was taller in the leg than I was longer in the arms. Remember this was hand-built. So, I needed a short top-tube, which would result in a larger than normal head-tube for the size bike and something that would look out of proportion. Look at this picture and you can see the same hallmarks.
5 - Bearing in mind the short top-tube, I do remember it being 21-inch or 21.5 inch so, if you measure from the centre of seat-tube along the top-tube to the centre of the head-tube it should be 21 or 21.5 inches.
6 - Similarly, the measurement of the seat-tube should be 22-inch from centre of BB to top of the seat-tube.
7 - Even tho I was riding road-races, I was predominately on the Track back then and resisted a double bottle cage set-up.
Billy, if these align I have my bike ..... There's enough in 1 to 7 that it couldn't be another one ....
My Mum still lives just outside Cardiff and my brother is often in Cardiff so it wouldn't be an issue to collect it from you.
You are dead-right, restoration of this is not going to be cheap and economically not worth it but to me it is. I have already lined-up a frame builder down here in NZ who is able to do the work for me (haven't told the wife yet of course) and restore this back to a beautiful state.
Billy, check these things out for me and get in touch, if you are OK with it, I'd love to collect it, restore it and ride it once again
