Blanco was a khaki-coloured waterproofing which you used to paint your cotton web gear. I'll show you when you eventually decide to visit London.
Gaiters are anklets made out of webbing; you tucked your trouser bottoms into the top of them, and they went down over the top of your boots. Again, show 'n tell sometime soon.
Shirrell Heath is Richard's village of residence, north of Southampton. Nice place, and of course the focus of acitivity for the Solent Club, which Richard chairs.

LRDG stands for "Long Range Desert Group", the model for the present day SAS. They used to take their trucks (most of which Canadian or American) thousands of miles out into the Western Desert in North Africa to conduct reconnaisance or resupply patrols. Quite a unique body of individuals, which, come to think of it, applies perfectly to the Shirrell Heath mob.
