PRECISION letter scale

Precision letter scale

This PRECISION letter scale has several marks. An elegant T logo is presented at both sides of the housing. At the back the name of the manufacturer is stamped in the surface: TRINER SCALE & MFG.CO. CHICAGO, U.S.A.. Other specimens don't have any mark at their sides. At some specimens it's a painted T logo. More recent ones just bear a Triner sticker or sometimes a more modern layout of the name Triner. At other backs of the Precision housing, beneath the manufacturer's name, it reads: PAT. MAY 1. 1906, & ABROAD. Also at the back of the scale is a little rotatable metal cover with the stamped in text: Regulating - Screw inside. Behind this cover is a little wheel to adjust this scale at zero. This is without great use, because friction during a following weighing action, will prevent a return to zero.

The range is 4 Lbs, subdivided per halve ounce. The whole dial of the Precision is crowded with figures of several postal rates. The dial is protected by a transparent cover of celluloid. Different dials exist, some specimens have some red figures and characters. A change in postal rates forces a change of the dial. This change is not an easy action. In the Triner catalog of 1910 a Precision scale is shown. One could choose from four finishes: black enamel, oxidized copper, aluminum bronze or full nickel plate. This for 2.50 USD, at no difference in price. The copper colored striping and spots belong to this scale. One also finds them on other American, and also on German, scales. I still don't know the meaning. The plate is flat or slightly slanting at the front and the back. Below some more photos of the Precision.
