(Elmira, MI)

Hi, I just found a colonial manufacturing grandfather clock at a second hand store for $25!

I would like help to identify age and what I should do before I attempt to wind it.

It came with all the original paperwork.
It is model 1615 movement 122 dial c1, below the 1615 is stamped 358.

Would love any help. Thanks
