My issue is that I have a decent shot-down RAF uniform (RAF Bomber jacket (which it's probably too hot for now), tan pants, genuine pilot's flame-proof flight gloves, and such, but my guns are german...
I have nothing so will have to admire the pictures Could you not argue that if he is shot down, rather then using his sidearm he decided to equip himself with some much better German weapons he 'acquired' while making his way back to friendly lines.
I totally agree, but it depends on how strict the rules of the game are; if you need to ID targets on helmets and guns, then guns are the easier to ID, and I wouldn't want to cause and hassle because of it.
Actually, if you would be driving from Reading, I could carry a lot more if you gave me a lift from Reading station as I wouldn't have to change trains and navigate the underground through London.
What station would your train come out at in London? If it is Euston then get onto the fast service from St Pancraes then head to gravesend were there are plenty of buses to Bluewater which is the quarry next to sandpit. Euston is a quick walk from Euston to save underground pains.
