Place breech in jaws and locate pivot pin in right jaw and line up with pivot hole. Push it in just enough to locate and then put plunger spring and plunger into their hole and depress and then push pin right through. Replace cocking arm and roll pin. Fit action in stock and tighten screws.
The safety catch on Webleys are not great. The mk 1 and some mk2,s are automatic but if you cut the bit of the safety catch off at the front (the bit the cocking arm pushes) then they become manual. On the mk 1 there is a shelf on the side of the safety catch that stops the sear from moving. On the mk 2 its at the back an stops the trigger from moving but these (mk2) aseem more likely to break off. The Hawk mk3 has the "wrap around" catch where the rear of the trigger cant move upwards because it hits the wrap around. NEXT THE HAWK MK 2 AND HAWK MK 3.
