Both desk cannons are in brass, with each cannon composed of a barrel mounted to a stock with cheek base, its mobility enabled by two wheels, each of which has twelve spokes, one cannon with the wheels secured to an axle via brass nuts and caps on either end, the other cannon using nickel-plated nuts, the wheels on each cannon functional, measuring 130 mm in width x 350 mm in depth x 210 mm in height. The cannons weigh approximately 2.5 kilograms for the pair. The cannon using the nickel-plated nuts exhibits nicks and flaws on one wheel. Together, better than very fine.
