I metered for box speed (ISO 80) even though the film is 44 years old so most of the shots are underexposed. Honestly, I wasn’t expecting anything because of the cross-processing so this is a pleasant surprise.
A minor tear-down to clean it and measure the aperture.
The whole lens/shutter assembly lifts off to reveal…
I wanted to get to the back of the lens to clean it but I couldn’t figure out how to remove the shutter. It turns out it’s just sitting there. The whole stack, the face-plate, lens, shutter, and felt, are held in place with the screws.

The outer shutter opens & the inner one closes so the aperture is already covered when you let go of the lever.
The time lever (right in the photo above) has a tab that holds the inner shutter open.
Simple is good. Simple survives. Other than cleaning the lens and a little gunk in the shutter, I didn’t have to do anything. This camera works as well as it did 77 years ago.
