So, I have this new to me doglock British musket reprodiction. Not an Indian one. Here's the post about it: https://www.muzzleloadingforum.com/...musket-supposed-to-be-and-who-made-it.185978/
The lock has a problem, maybe- I'm too ignorant to know if it is supposed to be like this. The tumbler, between the half cock and cock down position, has a sort of flat spot- actually a little depression. When cocking the lock there's a definite harder effort spot there, and when letting down the same spot interrupts the smooth fall of the cock. The sear nose gets hung up and bumps there, but the cock does go on and finish the stroke. My experience of sidelocks is that the fall of the cock is smooth, but maybe the early ones had an intentional rough spot? Maybe to soften the impact of the flint?
The lock is otherwise of, to my eye, good modern construction. Aside from this, everything works smoothly and there don't appear to be any spots where the parts interfere or mark each other. None of the springs rub on the lock plate.
I've added pictures of the lock inside, and as best I could pictures of the flat spot.

Sear nose is at the "flat spot"-
You can see that the flat spot is actually below the curved surface of the tumbler, it's not been brightened by friction with the sear nose.
I don't know who made the lock, I bought it second hand. I would think the fix, if it is not meant to be this way, would be to stone the tumbler surface out to a smooth curve and eliminate the flat spot/depression. I don't think heat treatment would be an issue, the sear nose just rests on the surface- although obviously the sear spring is very stout!
Thank you for your assistance.
