    I suspect it's likely that Euros will use a more modern manifold. For what it's worth, my flat bottomed Euros have V4Tec bands and the (just measured) spacing between valve centres is 185mm. OK, so according to the vernier it's 184.88mm, but that might just be how I measured...
    Thanks, I thought that might be case, but I'm not sure which bands are on it and I don't have it here since it's at the testing centre. I have sent them a note to ask...

    Never been wet

    I can put you in touch if keen
    Thanks - would be good to know the brand and sizing?

    He also has the twinning bands, again, never been wet

    Im guessing the manifold measurement is matched to the twinning bands

    Theres loads of drawings here - http://www.beaversports.co.uk/Catalo...?cat=twin-sets (Look at the 12L 232Bar drawings)

    I think that's the problem with the bands I've got. They are SDS which I think were sized for Faber 12's and the old style MDE manifold which matched exactly my old set up. But the shop testing them decided that one side of the manifold failed and I couldn't find spares. Even MDE say they no longer have any. So meant a new manifold and new bands... forget it.

    You're right about CD. All they've ever done is copy other manufacturers without actually understanding why the original piece of kit worked the way it did.

    Perhaps your Vernier needs calibrating.

    To be fair, hes lined the valve centers up by eye and managed to get it within 0.12mm thats pretty well calibrated eyesight!

    Seriously? Actually, a question. If the bottles are tested, then I guess there is nothing to prevent me collecting it all and see whether it goes back together myself. I don't actually "need" the centre to sort out the manifold issue?

    I have seen a lot of manifolds all over the world that are bent but functionally fine... yours presumably was fine till they told you it wasn't
