musket cocking mechanism part?

[Viddy]

I was hunting a local park that dates back almost 200 years, as old as the town. There are old cannons there and a war memorial and all through the town's history, everything revolved around this park. I found some old coins, some clad, and this....

It looks like it's brass or copper.
It has some green on it.
I put a quarter next to it so you can an idea of the size of it.
It was about 8" down
Could it be part of a cocking mechanism for an old musket or something?
The piece that is moon-shaped looks like it is supposed to be that way and not accidently bent, but I have no clue.

I don't know what it is, but I'm pretty sure it's not a gun part.

almost looks like it's a small pulley bracket for something. Does a cross bow or compound bow have something like this?

No, definitely not. Any of the mechanical parts of a musket would be steel or iron, brass is too soft. Brass may be used for triggerguards, buttplate, ramrod pipes etc.

hmmm...... true about brass. it's more cometic than functional on a gun.

The "cocking mechanism" on a percussion or flintlock is the cock - what we usually call the "hammer". They have very few parts. And, as noted earlier, are iron or steel.
