The small gyn has legs sixteen feet long, weighs about 8½ cwt., including the tackle, and is capable of raising with safety 65 cwt. It is principally used for mounting guns and howitzers on their carriages, and for dismounting them; and for placing ordnance of every description on platform waggons.
The large gyn has legs twenty feet long, weighs about 11½ cwt., including the tackle, and is also capable of raising with safety 65 cwt. It is principally used for mounting guns upon traversing platforms, and for dismounting them.
The rear of the gyn is the part where the windlass is fixed. The front of the gyn is the prypole.
Strength of Gyn Detachments.
One non-commissioned officer and ten men are allowed to raise and work the gyn, numbered as for gun drill.
The same number is sufficient to carry the small gyn. The large one should be drawn to the place where it is to be used in a hand cart.
At exercise the even numbers are on the right, and the odd numbers on the left.
