Re:
Few better shots.
Certainly plenty of brown on the surface. Wonder how deep that goes? Odd thing for me, the seat stays seem to be bolt on, don't think I've seen that before on a rigid frame.
Rear hub says Sturmey Archer Steelite and shifter is 3 speed. Looks to be integrated brake too so I'll try that out see if things still work.
I'll look for a date stamp on the hub to see if that helps with ID.
Gear shifter isn't connected to the hub, chain turns OK but is brown. Was pleased to find the seatpost slide OK so at least that's something.
