F-106B 59-0164 cockpit nose section, Timmerman Airport 22 Oct 2016.
Business end of one of the two scopes Frank made from PVC pipe and wood sticks. The screen is green tinted plastic and the graduation marks that are there but didn't show up is a decal. Frank got the measurements for the scope by measuring the scope on a 1:48 scale model of a 106 and he figured it out from there. He was three inches off the first time he brought a scope down to try it.
