Sold my metal hubbed coaster tuffs (black) for £20 back in the 90's, DOH
At the mo, it has a white SE seat on it, I have a black elina UL with fibre glass post, but can't get it tight enough even with the shims.
It's gonna be someone elses toy soon anyway, just got to get tough enough to part with it...
Cheers
