It's many moons since I last re-visited my 20mm WW2 collection, and some things have come as a bit of a shock. I've found FAA figures have indeed deserted across the pond to the States, but are still thriving, although it'll cost twenty five quid in postage to bring any of 'em home! I inquired if they had a UK distributor, which they don't, but would like one. I got in touch with a couple here in Blighty to sound them out, and got an even bigger shock... they won't touch 20mm with a bargepole!
Seems 20mm is going the way of the Dodo, being replaced with 15mm Munchkin scale?
