Old Ratchet Wheels and Old Repairs

I found these two old ratchet wheels while looking for a different parts. They show some interesting history.

This first one has divots put in with a punch around the square hole in the center, the hole for the mainspring arbor. This sort of thing is pretty common in old watches.

There must have been a lot of wear on those square edges. Punching like this pushes the metal inward, closing the hole some.

It's also possible that this wheel was adapted to repair a watch it was not originally for - a watch with a smaller arbor than the hole.
This second one is similar, but more interesting. Here, a punch of a different shape has been used to spread the teeth further apart.
