Diadem box camera No. 2

Apparently, this was made by Coronet, though the Coronet name is not mentioned on the camera itself.  Coronet, a Birmingham company, manufactured large numbers of cheap box and folding cameras from 1926 to 1967.  Perhaps the Coronet name was not put on the Diadem because it was a more expensive model. Introduced in about 1930, it takes 8 on 120, and has a single shutter speed plus B. The shutter is triggered on the way up and on the way down.  There's a fixed aperture reported to be about f/8.
