Thanks John, but Harfields, although they list them, have confirmed that their distributor is out of stock - I guess like a lot of suppliers they do not carry stock but order from their distributor when they need them.

So this is proving an elusive set. So does anyone have any other suppliers worthy of a try please? I do not need many, so if anybody has one or two they do not need I would be interested in swapping/buying if possible please.

Thanks
