Big Muskie. Big Muskie was a legend among machines while in operation. Also called Muskie and Ol Musky, the machine was a model 4250W BucryusErie dragline. It was the only model ever built, and took two years and some 200,000 hours to construct. When Muskie was built in 1969, it cost 25 million dollars. That's approximately 171 million today!
