Started disassembling: The tape is an artificial leather with thin foam underneath, and sticky tape underneath that . OK, so I have a little bit of cleanup on the bars ahead of me. So far everything is coming apart like the bike's brand new.

Thinking it through a bit more. I have a 40 year hatred of suicide levers, so I'm going to reassemble the brakes without them, include the lever in a bag should the eventual buyer want them back on. The seat is in a bit better shape than the scuffing shows, but it's rather wide. I'll probably swap it for a narrower seat, but here again include the original with the sale so the customer can swap around.
