While we're on the subject of dagger equipped percussion pistols, I have before me a picture of a double barrel (side by side) pistol made by George Wilbraham of London. The bayonet fits beneath the barrels (parallel) and is released by pulling back on the trigger guard. The blade appears to be only 3" long.
