Just a quick heads up because we noticed that Boyes (north of UK department store) have a range of 1/48th scale pre-painted clip together aircraft kits (in the toy dept, not the model dept)
Roughly £5 each there are the usual ME109, Spitfire, Zero, but also Mig-3, and a couple of "scout planes" that look a bit like a Vought Corsair. Each plane seems to come in a choice of two colour schemes, and for pre-painted they look quite reasonable.
