Fascinating. How exactly does this work? I am aware of apertures for the firing of signal pistols from aircraft but am just puzzled, from a technical viewpoint, as to how this operates. Is it a firing mechanism for flares? Or just stowage? If the latter, I am still puzzled! Presumably the flares are loaded from outside, plugged with wooden plugs and accessed from inside the cockpit? I am just puzzled!!

These are just for storage. They were loaded before each flight from within. In chase of a problem with, or fire, in one of the flares, you got rid of the problem by just pushing out the whole wooden assembly.
