    I know this has numbers etc. I've been told possibly scale for addition or tax computing But again, we haven't a clue what it is or what it was used for. If anyone can help us figure out what this is, we'd be so very happy

      Slide rule - there should be a makers name and number printed on the scale.
      Used for mathematical calculations prior to the computer age.

      There is also a category on here under "Office antiques" for slide rules

      Did you find the makers name on it? Keuffel & Esser, Dietzgen, etc.?? There is also a name on the glass frame but I can't read it from your pics.

      POST is the brand name -- sliderulemuseum.com/Post.htm?
      Frederick Post Co., Chicago, founded 1890, was a distributor of US brand slide rules, and other engineering supplies, which were typically relabeled standard products from well-known manufacturers from around the world.

      Thank u so much, now I can remember slide rule. It's been a long time since I've heard the name and my memory isn't the best ???? I will have to get it into better lighting to take some of the same pictures that it can be seen better on CW :)
