Top bits of kit and we'll worth keeping and using if they're in decent shape. I have a cyclops Roc which I bought in about 1987. At that time they were the ultimate gucci bergen as they were far superior to the military issue bergen. My Cyclops Roc did three winters in Norway, two jungle exercises in Brunei, trips and exercises all over the place including the Patagonia Ice Cap and has been in fairly constant use ever since. It is currently at Lancashire Sports Repair for new lid elastic and a couple of front buckles.
Great bits of kit, very well built in the UK from what we're pretty much the best materials available at the time. Worth preserving if only for 'ally' value!
