Wasn't the "camouflage" just a coat of green paint baked on much like the C No.67 telescope? I don't think it was a pattern of camouflage using different colors such as black, khaki, green, brown, etc. Maybe you could elaborate on the scope you have Warren? Green paint was also used on some service grade No.4 rifles during wartime and used in both the European and Pacific theaters of operations. I've seen a few No.4's, all Britishmfg with only traces left on the exposed metal but perfect paint on the underlying metal. I did have one produced at ROF Maltby dated '44 with about 98% of the green paint still intact overall. It looked like a factory job to me but I could be wrong. I always wondered if it was a green form of Suncorite but have to wonder as it doesn't seem to be anywhere near as durable.
