As the book states - it was Britains second biggest set and available for one year only (1953). IF any are owned by forum members - PLEASE show it - but bet one isn't. What it would be worth now is anyone's guess! Later in the chapter I showed an example from, Opie remarks that "a nearly complete set 228 was sold by Phillips (auctioneers) in 1981 for £480 - the same set achieving £,3000 in 1987 - just six years later! Nearly complete - mark you.
I wouldn't mind betting it's in an air-conditioned vault right now! more's the pity.
Good luck to you with your quest though Scott - you are certainly biting something off there - it will be a monster if you can do it. I'll help any way I can - as you (with other friends), have helped me get going here - and improved my hobby enormously. Thanks chum, johnnybach:salute::
