I know a bloke who seems to be very level headed but he's got a half-scale steam traction engine which he exhibits at steam fairs occasionally and in his living room he's got a 5" gauge steam engine which he paid £75,000 for and several original nameplates hanging on the wall including GWR Castles and Halls, probably worth half a million in total.
To be fair, that's not really Khaleds way, its just Barnsley's - been like it for as long as I can remember now!
