✅ SOLVED What kind of teeth are these?

[cdsieg]

Few more things found by where the old still was: Anybody know what kind of teeth those are (besides grinders)? Is that rock just a rock? The thing on the rock is brass like, the chain was found by a pond, nothing special about that, it was just in that days finds as well as the eye glass frames.

Thanks for your time, Cindy

I'd say that gear is a timing gear for a old motorcycle & would explain the chain as well (being chain driven).But after looking at it again I can't tell for sure cause now it looks very thin to me.

The gear is VERY thin, even though the chain was found in the same area, it wasn't anywhere near the gear. Also that chain is a lot bigger than what it looks, I will have to get a better photo of it tomorrow. I am not sure how big a motorcycle chain is, but this one is big.
Thanks for your thoughts!
