K-6 photographed circa 1914-1915. The date may be summer 1914 based on the fact the man on deck is in shirt sleeves. The long, low background appears to be the Cape Cod peninsula near Provincetown, MA. A number of crew are seen on the bridge and one person on deck. The boat appears to be flying a Squadron flag from a "pig stick" atop her #2 periscope and some sort of signal flag from her port flag hoist.

K-6 sporting her WWI era "Dazzle" camouflage at Key West, FL., 1917. The paint scheme was removed in favor of the standard haze gray before she deployed to the Azores.
