Sheldon Lathe Identification

I recently acquired a Sheldon Lathe and have what i can make out of a model number and serial number (all be it rather beat up and hard to read). I am trying to make a positive identification so that i can get a parts manuel and operations manuel before all the markings on the various name plates are gone.
The Model number seems to be GR72B and the Serial # seems to be GR25920.
I have yet to find any pictures that can help in the identification, but i can include a picture as received.
