Kirby Tradition - Clue to Verify If Metal Fan is Original

[kirbyclassiciii]

For all those of you that have a Kirby Tradition 3CB with the metal fan (cleaner unit serial nos. F000001 to F999999), have you checked the metal fan for a year stamp of either "79" (1979) or "80" (1980) to verify originality?

If yes, please try to show me a picture or two.

Thank you,



Ben
