You've probably been leafleted via your favourite model magazine, by Atlas Editions. They offer stupidly cheap models with the promise that you aren't locked in to a never-ending contract for more of the same.
Curious, I sent off for the Whittle's Burlingham Seagull coach, and it looks very nice. However, rather than read about it, watch this video of me taking it out of the box. It's what the young people are all doing and I'm assure this is the first step on the road to riches. Enjoy.
