Since your camera is older I would suspect that the chances of a housing being released is limited.
There was a universal housing that I looked at, could swear it was from Epoque or Equinox, but could not find it online. I had looked at those a couple of years ago and the held a wide range of cameras, but do not recall if it helsd your model. I may have the specs on it somewhere on an old computer in storage, but not sure. Reallly wish I could remmember, they were actually willing to customize buttons and so forth as needed and very reasonable priced. Of course depending on the model you maybe could not access all the funcctionss on the camera. Really wish I could find it for you.
EWA Marine does make soft housings for the camera, good to 100 feet/30 meters
