Original Art Deco desk letter scale by Bilateral, dating from the mid-20th century (circa 1930–1950). This elegant compact scale features a brass frame combined with a black enamel base. The clean geometric construction and curved weighing platform are characteristic of the Art Deco period. The rear is marked “Niet voor handelsdoeleinden” (Dutch for “Not for trade purposes”), indicating it was intended for office or private correspondence use rather than commercial retail weighing. The scale displays measurements up to 500 grams. A decorative and functional vintage collectible, suitable for interior display, office styling, or collectors of scientific and mechanical instruments.
