Obice da 105/14

The Obice da 105/14 modello 18 was a howitzer used by Italy during World War II. It appears to have been designed at the end of World War I, but that remains to be confirmed. It was originally designed to be towed by horses with wooden spoked wheels. Some weapons may have been modernized for tractor-towing with steel spoked wheels and pneumatic tires. For transport the box trail was supported by a small limber. Howitzers captured by the Germans after the Italian surrender in 1943 were given the designation of 10.5 cm leichte Feldhaubitze 326(i), although it's unknown to what extend they were actually used.

Both references listed below believe this gun to be developed in the 1930s, but this seems unlikely given the photographic evidence of the designation as modello 18. The box trail would also be very old-fashioned for a gun designed that late.
