So the K5 was announced in the July/Aug 78 reporter and in the News Flash October for upcoming 79 line so is anything in print on the discontinuation/switch to Spitfire 5 and when?, did it make it into any 79 catalogs sense they were printed then out months before?, weird how the Spitfire name was a backup for 77 & 78 after getting sued for Calif Cruiser and then they had to use it again 79 after getting sued for Klunker so if not for that there would have been 79 Klunker coaster brake also! they switched to Cruiser in 80 so sounds like they never wanted Spitfire at all, I guess sense it was name after a 40's fighter plane, not to relevant in the 70's like Calif Cruiser, Klunker, Cruiser!, maybe gives a little more credit to that thread with a Klunker single speed seeing that they were going to drop Spitfire completely for 79!
