Brass, enamels; measures 27.9 x 22.1 mm; weighs 5.9 g without the screw plate. Nicely detailed. Engraved serial number to the reverse.

Excellent condition. The enamel is literally perfect, free of any wear visible even under a 10x magnification. The details of the artwork are pristine. The original gilt finish is visible in recesses of the obverse and most of the reverse. The screw post is full length, over 8.5 mm, and includes the original mint-marked screw plate.

The Metallurgical and Chemical Construction Industry existed for only three years. Its excellence awards are therefore very scarce- there were probably only a few thousand of these ever issued.
