What's the serial # on the camera, it's usually located inside the front door that folds down to make the bed and focusing rails.
You can look up Graflex serial number ranges here: http://graflex.coffsbiz.com/serials.html to find both model and manufacture date within a year or so.
For a camera that features easily exchanged lenses, relying on lensboard material to identify models seems a bit dangerous. Blackened hardware will place you in the WW2 war years, as will a lack of chromed parts but less reliably, and neither says anything about what model the camera is.
I have to side with Team Crown Graphic based on what we know so far.
