I recently picked up a n excellent 2.5x to 8X, Weaver scope that I've not seen in my 40+ years. Beautiful shape, steel tube with what I'd call a tri-plex fine reticle. 3 each vertical & horizontal keaving a square open are in the center. The real interesting thing to me is the turret adjustments are integral to the rear " Weaver Adjustable Mount" and that totally surrounds the scope body. In other words it's a steel tube with that mount put in place before the power ring and eye bell are put onto the scope It presses a little bearing surface against the tube similar to Unertl or Lyman's Target spots.
Front ring is typical Weaver 1" with cross bolt bottom. Back also has integral cross bolt.

Would appreciate any info on this one. I can't find it in Weaver catalogs going back to the 60's.

Thank all of you in advance.
