Maybe for the same reason I don't trash can my first edition Weaver variable, a 2.5-5X. It has a third turret to change power. Glass is still usable but they were never dust or water proof. One even removed the turrets to install some rings. Maybe it is nostalgia, but I think it is neat. I may put it on a .22 from the same era. Jack
