This vintage bakelite scale is in good working order. It is missing the top tray, but I am sure a replacement can be found.
Unit of measurement GRAMM (from 0-500).
Inside the scale are the numbers: 1256/3. Also the letters PAG in a circle. There is large M and D with a letter S and the number 45 inside the large letters. Plus handwritten initals of J or H. All of these identifying marks are inside the scale casing and not visible from the outside.
