RE: anyone know what these would be worth?
Careful, read where the binos were made. A long, long, long, long, long time ago, when I was a kid there were some poro prisim black binos for sale real cheap that I bought that turned out to be some ok but not great glasses. I am not sure where they were made because that was not on the binos. The insignia was also not on the binos. I was ripped off. I bought knock-offs. Not saying they are knock-offs just check before you sell them to make sure they are represented properly.
