Description
The M1 was very similar in construction and appearance to the 155mm Howitzer M1. The only significant difference was its tube of 4.5 inch (114 mm) caliber. The tube had uniform right hand twist, with one turn in 32 calibers. The unbalanced weight of the barrel was supported by two equilibrator springs. The breach was of interrupted screw type; the recoil system hydropneumatic, variable length. The carriage was of split trail type, unsprung and had wheels with pneumatic tires. In firing position, the weapon was supported by a retractable pedestal. The gun was equipped with M12 panoramic sight.

Famous quotes containing the word description:
“The great object in life is Sensation—to feel that we exist, even though in pain; it is this “craving void” which drives us to gaming, to battle, to travel, to intemperate but keenly felt pursuits of every description whose principal attraction is the agitation inseparable from their accomplishment.”
—George Gordon Noel Byron (1788–1824)
“I fancy it must be the quantity of animal food eaten by the English which renders their character insusceptible of civilisation. I suspect it is in their kitchens and not in their churches that their reformation must be worked, and that Missionaries of that description from [France] would avail more than those who should endeavor to tame them by precepts of religion or philosophy.”
—Thomas Jefferson (1743–1826)
“Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.”
—Willard Van Orman Quine (b. 1908)
