Hstp : 47 R 8.6 - 16

On the UK website they say :

What means C19 Hotchkiss gun ?
From the hstp date it is a WWI gun.


19th century Hotchkiss revolving cannon, with five barrels - like a huge Gatling gun (although the mechanism was different). Usually fitted to warships as a defence against torpedo craft.
