The name on the left side is most likely one of the owners of the knife.

"7-5" on the sheath matches the knife, which would be a Model-7 with a 5" blade.

I'm awful at dating the knives, someone else will have to chime in. The 7-spacer arrangement isn't available today.

It looks to be in decent shape, gently used with some patina.
