I no longer have it on any rifles either. I once had a rifle fall to a carpeted floor with Leupold STDs. It shifted POI 7" at 100 yards.
But....in 1920, you couldn't just pick up a catalog or go to a website and pick out bases for your rifle, and the adaptability of the Redfield system was its virtue. Though its time is past, it fit a real need 60-90 years ago, when mounting a scope was a more difficult proposition than it is today! Like the Model T and the Apple II, it led us to the better systems of today. I want to wish it a fond farewell for the place in history it occupies.
