In 2001k I bought one left hand bearing, from a guy called Simon on the old list (his last one) .
I then contacted 8 Koyo dealers around Europe and found the right hand bearings in Sweden only and bought two for 120USD , and used one for a crank. At that time nobody could find the middle bearing.

In 2004 I think , there was another greek who found the bearings but I never got the ones I asked for.

For the few, here are the F3 numbers that Matt came up with on the old list
F3
Left - KOYO 83B569DA
Centre - KOYO 83B915L (L crossed out and GB engraved)
Right - NTN EC-SC 06A91 NC3 (C3 crossed out and C542 engraved)

He had the MC28 middle bearing as :83C137A
