Began cleaning, saw couple other details: Simplex derailleur is missing the plastic name plate, nothing but adhesive there now. Pedals are MKS.

Long term, bike will be a rider, I'll replace broken parts, and just use the existing components with different tires. Likely possible to remove splatter paint and bring back original look, but would be lots of work & I like its vibe right now! May clear coat to preserve the "art" prior to re-build. Don
