Hi,
I just had a look at that one on E-Bay, it looks very slightly different to mine (running numbers). As much as I would love to think these are worth £675 each (or anything remotely close to that), I cannot imagine that is the case. I don't really want to put them on E-Bay because if the market for them is thin, they will end up selling for next to nothing. I think I will swing past the local auction house and see what they can tell me.
The plus side, I inherited these so they don't owe me anything, and therefore I cannot miss what I never had !
Thanks again for all your help chaps, I knew this would be the place to ask.
