Brass, "cold" enamels; 49.6 x 27.7 mm. Near the bottom is the Cyrillic acronym of the school КАТУГА ("KATUGA").

Very fine to excellent condition. There is a tiny chip to the upper right part of the white enameled border and a few minuscule contact marks elsewhere, the latter practically unnoticeable to the naked eye. The screw post is full length, over 8.5 mm. The mint-marked screw plate is of the Soviet era and fits perfectly, although it is not original to this particular badge.
