pick-up stylus pressure scale
&
letter scale

This combination of pick-up stylus pressure scale and letter scale was made by Lenco from Burgdorf in Switzerland. The scale is delivered in a grey plastic tray with a transparent sliding cover. The back of the package has a short manual in German, French and English for the stylus pressure weighing and the letter weighing. The letter clip has a separate protrusion on which the arm of the record player can be weighed. Do the weighing near the needle. It provides a good approximation of the stylus pressure. The scale is largely made of aluminum. The scale is subdivided per gram up to ten grams. Above this only the values 15, 20, 30 and 50 grams are indicated. This is ample for a letter scale.
