This interesting article is accompanied by a detailed photo montage of a previously damaged skeletonised No.4(T) rifle, used as a training piece for budding Armourers to learn with and develop their skills. As Peter says "It appeared that this ‘rifle’ had never been finished as a ‘T’ as the front pad hole had not been drilled. During bead blasting after a hard life as a skeletonised rifle, it was established that the screw had sheared off and simply been made off level. Drilled out and extracted, it’s back to its former self. Waste not, want not as they say…". Other photos in the article show the clear interaction of the sear, cocking piece and trigger during various phases of its operation.
Hope that helps …
Regards,
Doug
