I'm not a pure Nikko collector but i own a nib Brat (box 1 and 2) and a Super Sprint. If you want see them, check the link below. The Brat comes also with a rare yellow card box.

Now i bought this nice motor and 100% new, never run. They are:
- UP WORKS 480SWM
- UP WORKS 240SWM Cheetah
- UP WORKS 240SWM Cobra
- UP WORKS 240SWS Cobra
The last pics are about pages of nikko catalog with the Nikko UP motor imported in Europe at time.
