Cargo pods are possible, but they seam small and oddly shaped for cargo pods, especially considering how much you could carry if you just removed the front cockpit and used it for storage, which is what they did to make the Type 14T, putting a cabin with 3 seats between the pilot and the engine. But as fuel tanks they are mounted very low for a WW1 era aircraft where they preferred to put the tank in the upper wing so gravity would help fuel flow.
Then I read that Pierre-Georges Latécoère conducted experiments in inflight refueling using Breguet 14's, so I wonder, given that we have two Type 14's in this package with almost the same paint but different registration numbers and one with these strange tanks and one without, were these supposed to be the aircraft used in that inflight refueling experiment. There the low mounted fuel tanks would not be a problem since of the experiments I have read about, it normally involved lowering a hose from the tanker down to the other aircraft.
