I was watching the funeral for Deputy Chief Fahy this afternoon. His caisson appeared to be a KME, and was obviously outfitted as a caisson, with a significantly modified hose bed and a casket platform which raised and lowered (sounded like a hydraulic motor to me), with rollers to allow for the casket to be more easily loaded and unloaded.
My question is this: was there ever a contract issued for a new caisson, or did the shops modify a KME (or Seagrave, if my eyes deceived me) for use as a caisson?
