 I own a CMP that served longer. My Ingersol  Rand Compressor mounted on a cmp trailer was not released from service until 1987. I worked on it up in Flin Flon in the early 80s when I went up there for ATIs. It is a 1943 model which puts it's service life at 44 years.Note that it was never a training aid or a museum piece, but an original in service equipment.
