I was told that it was rebuilt as part of their maintenance program and was just siting ever since- I have no way to verify that but that is what I was told. I was able to hook it up to my compressor and test it and it worked as expected and pumped strong and runs quietly but I do not have a large enough compressor to run it for very long (it came fitted with a quick connect for a typical pull behind towable diesel air compressor). Aluminum body is definitely a more manageable than the steel versions of this pump weighing in at only 115lbs making it portable for onsite pumping and water transfer.
