Btw, is that the original handlebar?

I don't have that much direct experience with them, but is that really the case, or is it maybe just an optical illusion?
That does look like an early-1970's Sugino crankset.

You're right about handlebars. The steel bars are 22.2mm, 7/8", like a mountainbike, which begs for some thicker tape.

Alloy bars are 24mm, 15/16" diameter.
The clamp diameter is always bigger, 25mm (French), 25.4mm (Japanese and other lower-level), 25.8 (TTT), 26.0(ITM and others) or Cinelli/Ambrosio (26.4).
