A friend of mine has a stevens 67 12 gauge. It has the typical problem, when it is locked forward and cocked it can still be manually pumped, it will not stay locked no matter what. I tore into it and found one broken spring, the slide lock assembly had been ground on and a bent cartridge stop, fixed everything I could, cleaned it real well and it still will not work correctly.
I am wondering if anyone has a picture of the trigger assembly as it is supposed to be as I might have installed it incorrectly, not that I would EVER do something like that. Specifically the springs that hold the slide lock assembly and around the hammer. I am starting to think the bolt might have just smoothed out and will not catch an edge.

Thanks.
