At the risk of self indulgence - on Keith's excellent website here
http://www.oldcmp.net/warby.html can be found a pictorial record of our first blitz encounter more than 40 years ago, at the sawmill in Warburton just across the river from my folks holiday house. Many enjoyable hours spent here photographing these strange vehicular relics from every conceivable angle - Keith has climbed high up in a tree for this one!
