OEM wheelset for 1978 was 700C Araya rims with Sanshin hubs, so there is a possibility they were replacements. The other possible non-OEM component appears to the saddle which was an Elina in 1978. It's missing the OEM brake lever hoods and toes clips and straps. The front QR skewer looks like it has been screwed tight rather that using the cam locking action, as the lever is in the open position.

Generally, my approach to paint is that you can never go back to orignal. Consequently, I start by cleaning, polishing and touch up. Then I live with it for a while to see if it's really objectable. If it is, then it's time to repaint.
