Antique Vintage Henry Troemner Apothecary Pharmacist Balance Scale

Description

Antique Vintage Henry Troemner Apothecary Pharmacist  scale. In excellent condition. Antique  made by Henry Troemner in Philadelphia, PA.  Great condition for age (see photos). Sticker showing owned and calibrated by the state of Louisiana in 80's.
Scratches and other wear. The glass piece under the scale trays is painted black on the underside, but some of the paint is worn/missing , chipped om left front corner.
The knob on the front is to stabilize the scale for transport (turning it all the way to the left stabilizes the internal mechanism, and turning it all the way to the right allows the mechanism to move freely, and the scale to function properly.  The knob on the right side of the scale operates a small metal fork inside the scale that can be used to slide the small sliding weight along the beam inside the scale.
The two front legs are adjustable to level the scale, but there is supposed to be a third leg in the center rear, which is missing, causing the scale to tilt toward the back.
Measures about 7.25" tall, and the base is about 14" x 7".
