It's actually a backwards 'C' joined to the leading edge of the 'W", with a proper facing 'C' joined to the trailing edge. Best indicators of the bicycle model will be the brand and models of the major components (derailleurs, brakes, crankset), provided they are still original.
Thank you for the quick reply! I have found the following identifiers on those parts
Front and back brakes: center-pivot sidepull brakes marked Gran Compe
Front derailleur: SunTour Cyclone (or Cuclone?)
Back derailleur: SunTour V
Crankset: Sugino crankarms; outer chain ring marked Sugino <52> Mighty Compe
Of course I don't know if this is original equipment, as the bike was used, but at least I have not changed anything in the past 40 years. :-)
