I love my impression kits and I have toyed with the idea of putting together WW2 and/or various Cold War kits but one thing which tends to hold me back is that I need something protecting my chest (health related) which inevitably generates some issues. The Lee Enfield No.4 which has been teased a lot over the past year or so looks incredibly promising.
Your kits look incredible. As far as WW2 kit goes I'll admit I've got a soft spot for the 352. Infanterie-Division from Normandy along with the kit used by British Para's during Operation Market Garden.
I've never really investigated the WW2 weapons but your write up indicates some great pieces of kit, with a bit of technical know how.
