Pair of antique tailoring teams

Spectacular pair of old tailor's squares; very large, hypotenuse of each 58 cm, made of wood, each foldable obviously complete with hinges. One is used for trousers and sleeves depending on the side; the other is used for the back and the front measurements. These are patented "Vianelli - Mestre" squares; as reported. Very very sought-after objects; must have for old tailors, laundries, fashion ateliers.
