Right, been busy getting things sorted, and now built into a functioning rideable bike.
Ditched the koski stem and black tatty bar for a Ritchey forcelite stem and bar, stem is quite tatty but functionally fine, and as a combo they are awesome. Setapost didn't fit, was too loose so have a 26.8m in as that's the correct size. Unfortunately I went to my bike shop and they only had this ugly as hell seatpost clamp so that's what is on it for now.
Been on one half decent length ride, and it is superb. Everything I hoped it would be all those years back. Took some photos today when I got it out of the shed, so you can see the full build - all M737.
Two things to change in the future - new 8 speed wheels (currently set up with 7 speed) and to get some lighter tyres. Wighed it on my scales with just my weight and then with the bike and it comes in at 26 roughly, which was a bit more than it feels like but then cheap tyres, pepporoni forks and the wheels must all add a bit of weight I suppose. Dont really care on the number though, feels springy and responsive and I love it.
