Huw, I am staggered at the volume of knowledge you have at your fingertips. Ah!,memories.

I suppose that Pilkington's have a statue of Roy Saunders in their vestibule for having created a demand which was only to enable specifiers to obtain safes which would resist technical drilling and scoping attacks that were quite unrealistic in terms of what was actually happening to safes and only gives unnecessary problems to the legitimate technicians of today.

Great post.
