Have you ever tried to strip the trigger unit on a Tempest?, it was nearly mission impossible until I discovered this little manual, it details every component in the pistol, how to strip it and put it back together, also contains a parts diagram and list of components. 16 pages of invaluable information. No profit in this one, if you want a copy, its only £1.50p and thats posted! (All this fee covers is the paper, copying, envelope and postage).
