I am currently trying to get one of these back to life. The electronic circuitry seems to be something like a very early version of what was later implanted in the (full format) Electro35. The circuitry seems to work more or less (under/overexposure lights come on at reasonable conditions) but the shutter either stays open forever or runs at top speed. The shutter blades are terribly gummed, and since there is a lot of corrosion inside it seems impossible to separate the shutter from the body.
It's a bit hard to read (even if translated by google) but it clearly shows that a leaf contact (on the right of the slide contact assembly) was misbent, maybe this was the culprit. The timing capacitor is OK, I replaced it by two tantalum capacitors (as usual on Electros it had an odd value of 3.9 micro-farads - 3.3 and 0.47 switched in parallel will do the job).
