US NAVY No. 48 Keuffel & Esser SLIDE RULE, 4081-3, With Navy Case, Vintage, Nice. In good condition, there is some writing on the leather case that did help me with some research. I assume JRP is Joint Requirement Planning or Panel. Also has patent pending listed on item. Any questions or details, please reach out, thanks!
