So, I am leaning heavily towards fake, at this point. But, to hopefully confirm unequivocally, I decided to post the question here. If they are fake, I hope this will help others avoid making a mistake in the future. If they are real, which at this point I doubt, then, well, that is a good thing.
I posted them for sale, because they eyecups don't allow me to use them comfortably vs the bridge of my nose. I am not quite a cyclops, but my IPD is narrow. I advertised them as Zeiss, because I thought they were. Someone pointed out that he did not believe they were, and explained why.
The initial problem with his point was that what he pointed out I had already considered and dismissed. I had posted some questions elsewhere a few months ago, and researched it as well. Previously, I had concluded that they were legit. However, he pointed out some other things, and has me leaning towards a conviction beyond reasonable doubt. I wanted to see if there are any other factors that will solidify the verdict one way or the other.
I had "researched" to the point that I clarified the serial number coincided/conformed with/to Zeiss' records. The number indicated a production date in approximately 1971. This information, along with, during PREVIOUS online discussions, information I was given, led me to conclude that these were legitimate.
So, let me have it. What do you think?
