I've toyed with a few old Redfields. Still have the WF 4x that came mounted on a pre-64 back on the 80s, in a box where it belongs. The last was a 3-9 I got when I traded for a very nice Remington model 6. That one was perfectly workable, but left when my pumpgun experiment ended.
No particular reason to replace one you have if it's still serviceable, but seeking one out, other than as a period-correct adornnent for an old rifle, is a dreary idea. Like the other guy said, the view ain't the best, and other stuff can go wrong leaving you in a bind.
Bullets and optics have come a long way. Take advantage of that.
