Dennis, we may well be onto something with the similarities between Century and Citation II and the Sprint 215 and 235. I'd almost bet the homestead they're the same reel and that the first iteration ( C & C II) never actually existed.
I just researched the catalogs. The only year the C II's were shown was 1979. In 1980, the Sprints were shown. Previous assertation seems confirmed. Always willing to be contradicted. Johnson also rolled the '78 Sprite 200 and the '79 Sprite 200A into the Sprint series in 1980, designating it Sprint 205. These l'il mini-spincasters are delightful machines, perfect for panfish and trout. Not too difficult to work on, either.
