And so, Fork issues notwithstanding, here's the finale of 5 months of weekends and a fair few workdays.
How it was at time of purchase.
And after many trials and tribulations with painting, "bodywork", powder coating etc.
Many thanks to those that helped with advice, especially Timoth with sage words (and items) about Hope hubs and brakes.
So what's original? The frame, the shock plates/insert and the seat-clamp. Everything else was sourced here as second hand or NOS, or FB pages. Spokes and nipples, cables, tyres and all bolts (except the main pivot bolts) are brand new. All bearings bar the main pivot are also brand new.
Frame is polished alu and matt silver finished, matt lacquered, which was never a factory option and the decals are older designs that the bike had.
To be fair, I don't know what that makes it. Is it a Retrobike or a custom build?
