Re:
Interestingly (only interesting if you hanker after old Konas that is) the frame appears to have been sprayed white originally - it looks too thick to be undercoat. The red has been applied and then the decals and then lacquer over the top. I've never seen that on a 1990 model before. I'm 100% certain it is original paint as some of the decals are transparent and it is one of the few red ones I've seen (the others from the same year are mustard with splatter and solid white) as shown in the catalogue. The decals are different from the catalogue. The paint really shines in the sunlight, maybe cost of the red finish was prohibitive which is why so many white ones without lacquer are about. The serial number is quite long so no clue if it is a late or early frame, only 'F90' at the start, confirming the year.
The forks are Spinner and are chuffin' huge - the head tube is 7" long! The frame is 21" centre - top of the seat tube.
