Here's the pictures you ordered.
Note: I noticed the brass spring on your shutter is bent differently. The 65mm distance I mention is a measurement what works with mine. I'm not going to tell your spring might need reshaping, but "it may" in order to work properly. Of course, you will know through experimentation.
The picture named Shutter1 shows the string in place when the shutter is in the fired (released) position. I first pushed the string through the hole in the hub at position 1 using a pointy toothpick, and then pull about 10 inches through so that you have plenty to work with. Tie a double knot at position 1 and pull the knot up tight to the shutter hub insuring the it will not pull through the hole. Insue the shutter is in the fired (released) position. Pull the string around the hub in a cw direction directly up to position 2 to meet up with the brass spring. You may have to pull the spring down to achieve the 65mm distance between the two points depicted. Tie it off securely on the brass spring at position 2. I made a loop there, and you may choose another method.
Shutter2: shutter cocked
Shutter3: fired with "T" lever only (timed)
Shutter4: completely closed by using the "I" lever (Instantaneous)
