Here is a Thomas Newton sidelock ejector gun. The strikers were both broken and it suffered from the butchered, buffed and heat-blued screws that so many self-styled gunsmiths are so fond of. Here's a tip for all of you, widening slots, rounding the edges, smearing the engraving with a buffing wheel, and heat-bluing screws DOES NOT make people think that you're and "English trained gunsmith", it merely makes you look like an incompetent twat.
The new strikers and the new striker retainer and lockplate screws. The screws will be case hardened and lacquered, as they should be.
