Edit: Sorry, I just noted you've drawn a line on this but I've just picked up on your amazing project and just want to add my thoughts.
Bl00dy hell!! I cannot believe there are fellow modellers out there with this attitude!! We all come from different backgrounds but share the same hobby. Some of us may be fortunate to have funds whereas others are modelling on a shoe string, but at the end of the day we do it for the pleasure it brings, as with any hobby!
I'm sure Simon has worked hard all his life and is now achieving a lifetime ambition so how dare anyone deny him that.
I've only just discovered this thread and am envious as hell but highly respect the work and skill involved to achieve his goal.
Keep up the outstanding work and I hope I can see this layout in the flesh one day.
Regards, Deano.
