These came from the small North Dakota town of Luverne. An old gas station was being torn down and the guy that I bought these from said that they were underneath the floor boards. If he would've been a day later then these lenses would've been gone to history. I talked with Scott Benjamin (scottpcm) about 3 years ago about these lenses and he said that they were a new find. The lenses do have water marks that you can see in the pictures. Can provide more pictures if requested and my phone number is 701-425-1244. I'm asking $400 for the pair and I will go in order of PM's and not by postings. I would prefer local pickup in Bismarck, ND in fear of shipping but it could be arranged through the Oldgas shipping service with other members.
