Model of a Gun and Carriage

Entry

Model of a gun on a special carriage, mounted on a base with a gun port.

The wooden model of the reinforced gun, 37.5 cm long and painted black, has five reinforcements diminishing in diameter towards the chase. It is not bored. The button consists of two lugs with a horizontal ring between, through which runs a vertical pole which is a schematic representation of the elevating screw. At the base ring the gun has a second pair of thin trunnions. The carriage is fixed to the base. It consists of two cheeks extending above the gun and connected by cross-beams on the deck and brass cross-struts above the gun. The trunnions lie in slots in which they can move up and down. A second pair of cheeks that can move up and down, situated outside the first cheeks, have horizontal slots for the trunnions. The trunnions thus lie in the intersection of the slots of the inner and outer cheeks, which can vary according to the elevation of the gun. The outer cheeks also have slots at the rear, in which the small trunnions attached to the base ring of the gun move. The result is that the gun can be elevated to any position without changing the height of the muzzle: the main part of the barrel moves up and down, but the muzzle stays at the same height, enabling the use of a small round gun port.

The model provides no details about the movement of the carriage in recoil, for loading or for training.
