Hello PS. Place bolt flat on work bench. Take a dowel or screwdriver and place tip in the back end under the dust cover. Push the bolt down until the dust cover is out of the rear slot then strike the dust cover off to the rear with your fiberglass hammer to totally free the cover. Unscrew bolt head and dismount firing pin with the same tool as you use for your SMLE or No.4. To remove safety put the cocking piece in a vice (the long rectangular part as its hard). Put the safety lever at a 45 degree angle. Tap out the safety using a brass drift from the left side. There is a spring loaded pivot pin now evident in the cocking piece that secured the safety. Place cocking piece upside down and it may drop out or just tap the cocking piece on a piece of wood and it will fall out - don't lose it. Any problem just bring it to my place in Burlington. JOHN
