Just catching up on this thread:
mojo - saw the ones on the bay but the grey colour wouldn't look right on my bike. However they went for £7.20 including postage (pretty cheap).
masha - thanks for the offer but I'm really looking for the stubbies (straight ones).
yo-eddy - thanks for the offer, but I prefer the clamps on the later ones. I know it's not as retro as it could be, but I just prefer them. I'll keep these in mind though if no newer ones turn up.
Have attached a picture of the style I like, these are the grey ones from the bay, but looking for silver, red or gold (for 3 different bikes before you call the style police!).
