Thanks - mostly dust and one broken spoke - I am so tired of deep rust.
The shifter is shown in the 1968 catalog pic as being a white T-handle so this one is a bit of a mystery. The saddle and serial number dial this bike in at 1968 specifically so not sure if it is stock, factory substitute, or owner replaced. I would imagine the lucite ball was black at some point.
It is no big deal in the scheme of things, at least it is there and it looks pretty cool. All in all the bike looks 99% OEM.
