I'm reasonably good with firearms but I'm out of my element identifying old scopes. I got this recently and am trying to figure out something about it. Google says this model of scope was used on springfield sniper rifles, but they dont have the larger objective, it also isnt marked in any military way so I suspect that would be too good to be true. Only markings are the weaver 330 el Paso texas on the data plate, and R.A. Litschert I believe on the objective. It's in good shape optically, it has an extremely fine crosshair. Also has leupold style mounts.
