Hi everyone! First timer here, so hopefully I get the process right. I really need some help identifying a "vintage" shower mixer valve. I am pretty sure it is Kohler, but after poking around here a bit, I guess it might also possibly American Standard or Speakman. I am going to attach as many pics as this page will allow me. I need to identify and hopefully find a place to refurbish or replace the parts, so I can get this old shower back to its full glory. Sadly this shower had the most wonderful water pressure in the whole house before it died on me. The house is 72 years old, but I do believe this particular bathroom was maybe remodeled at some point..possibly the 70's? The whole room (including the shower) had floor to ceiling 1x1 multi greyscale tiles and a lovely sun roof...very unique and we hope to not have to tear out any of the tile if possible. Please take a look and let me know what you think. In a perfect world, I would love to find all of the parts in the pictures, but understand that might not be possible. Much appreciated!!
