Hub is 11/65 so that fits. Fairly early Series 2, then.
There's about a degree of rotational lash in the steering. Is it correct that this can be fixed by repositioning the splines on reassembly, or is it worth replacing anything?
Plan is to strip it, get the frameset powdercoated (did they come in any colour other than blue? Metallic red? I don't like the blue) coat all the heavy chrome bits in vaseline and store them away in case anyone wants to do an authentic resto in future. Then replace with alloy bits where possible. I have another mint FW hub I built for a 4-speed Brompton idea years ago, but it was never very successful.
I have ordered a lot of Plus Gas and a super-long Philips no.2 screwdriver
It rides, but it feels as if it really needs a complete overhaul rather than an adjustment. Clunks aside, the front suspension is much better than the TSR's. The TSR friction damping overlooks the fact that static friction is higher than sliding friction, so it will always start moving with a bit of a pop.
