If you're really lucky, an old fixed power Weaver 6X. Don't see them much anymore though but it would be perfect on a gun like that.Ammo is easy. Buy any you can find.
For a scope, I'd eBay up a nice old Bushnell Banner or Sportview fixed 4x. Something from the time period correct for the rifle.
Then I'd enjoy the heck out of owning and hunting with it.
