Thank you for the article, I have read a number of them, but what I need to know is where (if they even have them at all) the set screws are located on a pair of Zenith 7x50 binoculars. These are the old standard porro Prism type. It's possible they don't have them and would have to be sent to a factory to have it broken down and lenses set and glued. I'm hoping they have set screws located somewhere that I can then adjust to focus. All the articles I find about Zenith binoculars come from Europe. I don't think they were very big here in popularity.
