1. The best bit of kit ever issued was the No.4 Mk.1.
"The Lee Enfield Rifle is the reason we still speak English."
2. The next best bit of kit was Black Bodge Tape.
3. Third on the list is that Compo Can Opener widget and the Compo Sausages to which it gave you access.
I was rather fond of the previously owned "Trog Boots", Seaboot socks and ragged old "fishtail" Parka held together with black bodge tape I was given to wear out on the Line at Waddington. Nicely non-military, our kit made us look like a gang of Irish Navvies.
