Theater binoculars in mother-of-pearl and brass, 19th century

Very pretty pair of theater binoculars, in mother-of-pearl and brass, dating from the second half of the 19th century, stamped 12 glasses. An eyecup is missing at the back of the pair, so they can only be used for decoration as is. Traces of wear on the mother-of-pearl only located on the interior sides + slight damage to the hard plastic surrounding the eyecups. Some stubborn dirt on the inside of the front glasses. Length: 11 cm depth: 7 cm weight: 0.225 kg.
