I'll suggest the folks who have first hand knowledge of what scope went on a 1949 M-70 are fading with our Greatest Generation.
My impression of the time,which could be wrong:Back east big game hunting was typically in the woods with iron sights.
The scoped rifle passion was about woodchucks and crows.The ultimate varmint rifle!And the Lymans,Unertls,etc.external adj target scopes.
But as you headed West to Mule Deer,Elk,Pronghorn,Sheep,etc,a bolt .270 or 30-06 set up with a Weaver K-4 was pretty standard.
It would darn sure be a representative correct scope for the time.They are easy to come by,and you can get them serviced.
Looking on E-bay,you can find old Unertl hawks and Falcons,but I don't recall seeing rifles with them installed.There are Lyman All-Americans .
I have an Alaskan and an 8x All American.I like them.
If I'm not mistaken,Kohlmorgen may have become Redfield in some way.I only say that because the scopes look so similar.
I think maybe what shows up on e-bay is also an indicator of what was selected,and what survived.Unless,of course,its NIB or nearly so.
