I visited Barrett Battery in Prince Rupert BC in 2003. Here is a pic and a link to some I've posted.

Barrett Point Battery
(1939 - 1945),
Three 6-inch MK12 guns on MK7 mounts were temporarily emplaced here until 1944, when three 6-inch MK24 guns, two on MK6 mounts and one on a MK5 mount, were emplaced. A 6-pounder Hotchkiss gun was also here, as well as two 40mm Bofors AA guns and two searchlight positions. The observation post, plotting room, and magazines still exist, but overgrown with vegetation. The ruins of the fire-command post still exist.
