I figured that it'd sky-rocket towards the end of the auction and just kept an eye on it out of curiosity (sure these have been going for over £100 when they've come up before). When no-one had bid with 7 minutes to go I could feel the old heart start thumping. Then 3 minutes and nothing. Then 1 minute, so in went a bid.

Just have to see what's what when it finally lands on my desk and Mr Screwdriver gets a chance to play
