My second KW Patent Etui, this camera has the only purpose to fit the double Protar 18cm (equal to 10,5cm) plus a roll film back.
I manage to place the Compound shutter in a way the camera can be close and even being the Protarlines more deep than the usual lens for this camera, it closes fine.

KW Patent Etui 6x9.
I placed the ground glass of the KW backwards (matte side outside) to calibrate the lens according to the Rada film holder and make the new distance markers for this lens. Infinity, 10, 5, 3, 2, 1.5 and 1 meter.

New distance marks.
This is the test roll, my last Acros 100 film. Composition of the pictures has been done by prism finder, placing the camera against the chest and looking from above TLR style. Hand-held shooting but one.

This one was focused by ground glass, I nailed the subject to focus. I cropped the photo because it was so dark inside that a f6.3 aperture was not enough for a good composition. 7 seconds @f8.
