That's quite some few...
Tamiya makes several old British infantry kit
Dragon makes some great sets, being SAS commandoes, 8th Army North Afrika, a larger squad on manouvers, and such. Pretty awsome kits which I want pretty much.
Master Box recently released two kits of Paratroops, both set in Market Garden. I ordered these kits yesterday, and if wanted I could give you feedback. One of the kits is where two medics are treating a wounded man (One of the medics are infact offering him a fag) and for the first time in plastic, a glider pilot! The glider pilot is also wounded, but both the men only have some bonefractures.
The other kit from Master Box is 3 standing British parratroops, two are waiting and the officer talks to a civilian about directions. The civillian have a double barreled shotgun over his shoulder and a dead rabbit down his belt...
(I don't know why I talked so much about those two kits... sorry.. I think).
Now other manufacturers may do it, and I know several of these Resin manufactureres do have several British.. But you know, British WWII isn't alot of in plastic.. But I do see it's expanding.. mwahahaha!
Hoped it helped!
