4x5 Press King Camera
Here is a very unusual camera, a 4x5 Press King (c1948-1950). Made by the B&W Manufacturing Co in Toronto, Canada this model seems to have come and gone very quickly. I can't find any information about the company at all.

  

Although made of aluminium and roughly comparable to the Graflex Crown Graphic this camera doesn't appear to be overly strong. It does have a revolving back which is click-stopped at 90deg intervals and has the usual press camera movements. This one is fitted with a De Mornay Budd 3-cell flash with the adjustable parabola reflector.
