    Is pix 1 of the 2 in your post above the first picture you made after removing the face plate? if not post it please.
    It is never a good idea to operate a shutter with the face plate removed unless you have a service manual that instructs you to do so during reassembly.

    Google: prontor press shutter repair you will get several potentially useful hits.

    yes, pic 1 is after removing the face plate (it is on the right of the first picture).

    my issue has become specific to the resetting of that spring on the main timing gear. (if that's what it's called)

    I've looked at a lot of articles but none with that point yet...

    Thanks

    See: http://phasmatisapparatus.blogspot.c...ce-manual.html the 3rd manual may be of help. Although the manuals are for rim set shutters and yours is a dial set shutter manufactures follow similar mechanical designs from one model to another. I do not think the spring goes on the delay gear train or the set dial. A lever where a spring goes usually has a notch that the spring sits in but not always and the case will frequently have a grove that the spring end lays in. The fact that you say it popped off when operating the shutter with the cover off suggest that no other internal covers need to be removed. It does suggest that the spring goes on a lever operated by the trip lever or a lever moved once the shutter has been tripped.

    Am I correct you removed the cover, cocked and tripped the shutter, the spring popped off, you made the picture?

    i believe it popped off after taking out the mechanism that holds the three gears down and then tripping the shutter. Then i took the picture...

    I was trying to find where the resistance for restoring the shutter blades was coming from - as they wouldn't close properly after tripping the shutter. (The linkage wouldn't fully reset - so it's not just dirty blades)

    thanks for the help so far.

    Pix 1 does show the spring but it is very hard to see. The three gears are the delay timing gears and pallet. At the red arrow in picture 1 is the center of the spring, the long end goes to the left between the case and delay gear cover post, the short end goes to the right and rests against the case. The bend in the long end at the center faces the case.

    The cover over the shutter blades will need to be removed to realign the shutter blades. The shutter blades will only come out of position if they or their pivot pin breaks or the retaining plate comes loose.

    I can repair the shutter provided I receive it in its original assembled state.
