Adrian helmets, these are Belgian

The Belgian helmets are basically the same as the French helmets but with a Belgian Lion’s head insignia and unique mustard brown color. The one on the left is a large size and the one on the right is small.The helmet on the left was manufactured by Compagnie des Compteurs judging by the type of rivets used and the shape of the comb. The helmet on the right was manufactured by Delmas using the same details.The inner view of the left helmet shows it is just a shell without a liner, the only thing of interest in this photo is the soldier’s ID number stamped on the rear visor.The smaller helmet has a first pattern liner of black dyed leather.
