There is an original unrestored Canadian Clearvision in the auction on Saturday, its been blasted and primed, it has 2 awesome original triple etched cylinders, heck I even found the curved glass that goes in the ad glass frames, there is nothing needed to find. I agree I like these better than Wayne 492s, they are just so massive, everytime I get to go see the one I did in Shell 2 years ago I just can't believe how big it is.
