Last night I saw a Redfield 6-18 on Ebay for $130. The weird thing was that it had 3 reticles which were independently adjusted. The scope had 6 turrets. One set at the middle of the scope and 2 sets near the eyepiece. I wanted to buy it cause I figured it was collectable but could not bring myself to spend the money without knowing its value. It sold very quick. The description stated that it was a Redfield 3 reticle scope used in the 1983 pan-american games. Anyone ever heard of this scope?
