bilateral letter scale

This bilateral -towards the two sides- turning sidewards, letter scale does not have a mark. The lower chart goes from zero up to twenty grams. The upper chart starts at twenty grams and finishes at two hundred and fifty grams. Below the subdivision is per gram. The upper chart is subdivided per five grams. The plate has graceful cut outs. More letters scales show this pattern. For instance, also this plate design is at the bilateral scales in which an Austrian patent number is stamped, and sometimes also a Hungarian and two German patent numbers.
