captain-price-official:A view of the “Land Excavator, Trenching” otherwise known as “White Rabbit No. 6,” “Cultivator No. 6″ and “Nellie.” Developed in 1939-40 in anticipation of a redux of the trench warfare of WWI, this machine was meant to dig a trench across no-man’s land for the infantry and other vehicles.
