The only info I have is that it was built as SN-1 for the USATC. Standard model 2-200. It was scrapped about 1971. I recall a conversation with John Henderson that at some point it was on one of the Air Force bases in Alaska and there apparently was some question of ownership ARR,US Army or US Air Force. I don't recall any details of that. I believe it was always lettered for USATC until scrapped.
