I'd that really like to find one of the weaver k4 classic or whatever they called them, just be over 10 years now when they came out. They were a near perfect copy of the k4 in steel or aluminum tube but with modern glass. I really wanted one but they were $400 or so, one would be perfect for the pre 64 m70 I'd like to update but not loose it's classic looks.
I may look for a luepold m8 4x they were nice scopes, but bring good money when they lol up. The Lyman all American were really good.
As luck would have it, there is a K4 Classic up for bid on Ebay right now. www.ebay.com/itm/234346747602?hash=item36902796d2:g:4kcAAOSwLkFhtT3F
