This is a classic mechanical balance scale commonly used for classroom, science lab, education, hobby, and measuring applications. Includes the hanging pan/tray assembly shown in the photos.  The scale is in used vintage condition with cosmetic wear from age/use, including dust, discoloration, marks, scuffs, scratches, and writing/number marking on the base.
