Do you have the whole kit, including the stand? That would increase the value, but would make ebay a harder place to sell. These are very large cameras designed for permanent installation, so freight will be a limiting factor.
What kind of lens? There are some lenses out there that will be worth many times over this camera, and the camera itself, which isn't worth a heck of a lot, will only slow down your auction. It might be worth looking into having it restored, but I don't know if this is a rare enough camera to make it worth it - I have my doubts - it's not a Deardorff.
