Hey Bil
Just so you know, I regard you, Gerald Wingrove and Andy Mathews as the foremost builders of our time, and the reason I got into this hobby.
Apart from the new interests that you mention, I'm sure that building the next show-stopper must be a daunting prospect for you, seeing as you set the bar so high already, but I really hope to see your work again soon.
Hope you get your asking price for this model - goodness knows, it's worth every penny.
