Benson Dry Plate camera - Factory specs or Frankenstein?

SO... I bought this on ebay several years back but the mystery still remains. How close is this camera to it's original form? Was the top of the camera altered to allow for the street photographer to take more pics on a larger paper roll? The knobs do not look original or matching. I have no idea what lens was originally used (missing now).

I would like to try to restore this camera if it is worth my trouble. McKeown's has no pics or mention of this camera. I would appreciate any information that anyone might provide provide.
