The Canadian and British Coast Artillery in WWII also had a twin six-pounder
for shooting up small attack boats. A complete and operational one is on
display at Fort Rodd Hill National Historic Site near Victoria, BC, CANADA.
This one had been given to Norway by Canada in the 1950s when we shut down
our coastal defence, and later re-acquired from Norway for the historical
display.

Manual loading, but the breech slams shut when shell is slid in as I recall.

Twin barrels - side by side, in a turret.

Photos of this turret are on my web site at:

For those in the BC and Washington (state) area, there is a military
encampment for living history at Fort Rodd Hill on May 19-20 (Victoria Day
long weekend in Canada). There will be some military vehicles, military
tents, weapons, people in uniforms (1860s-1950s). If interested in
attending, contact me off list at colin@pacdat.net FREE for people in
period uniforms. Free camping on site. VIP tour of old fortifications
(1890s, WWI & WWII zones at the fort including an underground Command Post
bunker.
