With the locks cocked and the gun open or with barrels off, the pins are free to move in and out in their holes. My question is whether anyone here knows if this gun originally had retraction springs or not -- i.e. would anyone have a similar gun and could they tell me if their guns have retraction springs for the firing pins. There is another thread here where two fellows had similar guns -- "duck billed" back-action sidelock W&C Scott and Son guns from the 1880's. One fellow posted pictures of his and it is only a few S/N's earlier than mine.

I will pay some attention to the shape of the nose of the firing pins, and the timing of the cocking on opening, thanks to your advice, 2-Piper.

Best Regards,
Tony Lowe
