Sight Screw Hole Spacing

I received a 30-30 barrel today for a FIE single shot rifle. It is D&T for sights but missing both. Front mounting screw is broken off. My main concern is that the rear sight holes are .875" on center. Anyone know of a particular sight or brand that matches this dimension?
I've been cruising eBay but most are 1/2" or slightly more. Any help?

could be for Unertl, Lyman, or Posimount scopes, if the mount screws are close to 7.25" between centers
usually the rear mount is .860 screw centers, and front mount is .560 screw centers

It's got a scope rail machined into the barrel over the chamber; these screw holes are in front of that, down off the chamber area. I'll do some searching for sights with .860" hole spacing.
