Decock (pull triggers on snap caps). Cranked tierod protruding left lock leftie loosie to remove. If lockplates are not "varnished" in by resonified lube/finish, the small tierod once unthreaded may be enuf to push out the right lock. If so, small dowell or similar inserted from right side thru inletting may push out left lock without damage. If you meet resistance, a light shock (tapping against padded surface) in the area of the action bar (forward end of lockplate) may loosen the locks. Do not pry them out! as damage faying wood will ensue. Remove triggerguard tang screws, lift tang clear of mortise and rotate (again leftie loosie) to unthread stud forward of triggerguard bow. Remove hand (under triggerguard) and wrist (under toplever) pins (machine bolts). Pull stock directly to rear.
