A 1959 Unit 617 Crane/Dragline and a 1952 Unit 614 Power Shovel at my Grandpa's place.  Once I get these to my new house I plan on stripping them down, fix any cracks/rust, re-paint, lube, and then dig a small pond with them.  There is also a boom extension hiding in the grass somewhere around there, but I'm not sure what shape it is in.   Should be a good project to last me a couple of years!
