In WW1, the Italians found themselves short of heavy artillery and were forced to rely upon some very old weapons. The Cannone da 149/35 was already obsolete when it was introduced in 1900. It lacked a recoil system and instead relied upon wooden ramps and a heavy box under the trail to handle the recoil. This forced the gun to be re-laid after each round making it very manpower intense and giving it a painfully slow rate of fire. However inadequate and obsolete, it was better than nothing. Shockingly, this weapon was still in use by the Italian army in WW2.
