Winchester and Colt (?) cartridge boards

I was checking on the Buffalo Bill / Winchester archive/museum website and painstakingly loaded these 2 boards (basically patchworking them back into what you see below).


The first one seems to be the most interesting though some cartridges are missing unfortunately.
Is anybody able to date this board and ID the larger calibers?

Anybody able to date this board?


The Winchester board is 1879

Sig, thanks a lot! How did you figure this?

Talked with Dan Shuey. He had studied the board at Cody.

Was he maybe able to say something about the other board and the cartridges there?

No info on Colt board.
