A very good gilt brass and bell metal gyroscope by Negretti & Zambra, c1865. Constructed in brass, bell metal and steel, flared base with stem pivot and signed by the maker “Negretti & Zambra, Instrument Maker to Her Majesty, London.” Outer gimbal with release screw and transport keeper; inner gimbal with steel pivots and accessories; gilt brass rotor set on a steel shaft.
A truly wonderful thing…Acquired in essentially untouched condition, the instrument has been stripped, pivots polished, the rotor reset. More time has been spent admiring and playing with this than sensible. A rare item, especially by this premier London maker, this is an object with great aesthetic charm, scientific interest and very collectable.
