Dannevoux. January 31, 1919 ) near Verdun( This Howitzer is of 38 cm caliber and was manufactured in Pilsen, Austria in 1917. It was captured September 26 by the 319th Infantry 80th Division. In destroying the gun before leaving the recoil was unfastened and a charge exploded which threw the base cap weighing 2 tons over 300 yards and the breach block through a 2 foot stone wall. The gun is to go to West Point, U.S.A. The gun had a compass bearing (magnetic) S 31° E and was used to fire on Verdun.
It looks to me that this howitzer is the same model as found in Vienna museum see my article
