[quote=“sksvlad”]I just want to add this old “lost” topic since it has cool pics.
Thanks for the thread on the 37-85 shells.
The Winchester is for a Hotchkiss gun. Found this: The term “Hotchkiss gun” also refers to the Hotchkiss Revolving Cannon, a revolving barrel machine gun invented in 1872 by Benjamin B. Hotchkiss (1826-1885), founder of Hotchkiss et Cie. It was a built-up, rifled, rapid-fire gun of oil-tempered steel, having a rectangular breechblock which moved in a mortise cut completely through the jacket. It was designed to be light enough to travel with cavalry, and had an effective range beyond that of rifled small-arms.
The revolving Hotchkiss cannon had five 37 mm barrels, and was capable of firing 43 rounds per minute with an accuracy range of 2,000 yards (1,800 m). Each feed magazine held 10 rounds and weighed approximately 18 pounds (8 kg). The cannon was accompanied by a horse-drawn ammunition limber, which held 110 rounds plus six loaded magazines, totaling 170 rounds. 
Hotchkiss also produced a range of light naval guns and, in the 1930s, anti-tank guns. The naval guns which originated in the 1880s were mostly 3 pounders and 6 pounders and originally were widely used (by Britain and Russia amongst others) for close-up defence of major warships against small craft armed with the newly invented locomotive torpedo. When improvements in torpedo range made them obsolete in this role, they continued to be used as small-craft armament up to and including WWII. In WWI the British motor gunboats which won naval supremacy from the Germans on Lake Tanganyika were armed with the Hotchkiss 3 pounder and the Hotchkiss 6 pounder was adopted by the British army for the first tanks. During WWII the 6 pounder was the main weapon of the early units of the numerous and successful Fairmile ‘D’ Class motor gunboats of the Royal Navy, not being entirely replaced by more modern weapons until 1945.
