Armstrong 100-ton gun being lowered on board of the Italian transport ship Europa, United Kingdom, probably 1870s.

This was a 17.72" muzzle loader as seen on the Duilio & Dandolo Italian predreadnought battleships, the so-called 'monster gun' that defined a short-lived era of battleship construction.

Battleship HMS Valiant in floating dock at Invergordon, late 1918 or 1919.

Quote from http://www.theinvergordonarchive.org/picture/number1462.asp:

"The gun tampions have a cockerel emblem confirming that she is H.M.S. Valiant. The flying-off platforms were fitted to the ‘B’ and ‘X’ turrets in 1918 so the date of this picture is either late 1918 or 1919."
