General L-boat photos
From PigBoats.COM

A small photo of three L-boats at an unknown location, probably in the spring or summer of 1916. This is definitely a pre-WWI photo, as these boats do not have the installed "chariot" style bridge structures.

Six L-class boats moored outboard of their tender in Queenstown, Ireland, summer of 1918. Left to right is L-3, L-11 (with bow planes rigged out), L-10, L-4, L-9, and L-2.
