The above link should take you to an interesting article about the
DUBRONI No.1 CAMERA
The cutaway drawing at the bottom of the article explains the workings.
I shall try and find a photo of an actual camera that has been sectioned to show the insides. I know I have a picture in a booklet some place.
With the original camera you could look through the lens and view the plate developing by opening the back flap to reveal a red safelight glass.
I think someone has tried to reinvent the wheel.
Cheers.
