Assembling the dials on a dial set compur?

[TheYoungPretender]

Hi!
I went through my shelves and found an older dial set compur shutter in an odd size half assembled. I've had no issues (yet) putting it back together apart from installing the mode selector dial as I can't seem to work out how it is supposed to attach.
In addition to the dial there is one screw and a washer. The backside of the dial has a very short locating pin which I assume is supposed to keep it from turning further than the cutout marked in yellow in the picture. Would the correct order to place the parts be: Screw, dial, washer, faceplate, shutter body?

I also wonder about the attachment of the screw to the shutter body. Inside of the shutter, marked in blue, is the mode adjusting lever. If I push it to the top it is in instant mode, pushing it down moves it to bulb and open/close. Is the screw coming through the faceplate supposed to thread into the cutout on the lever marked in blue? The other screws seem to have some kind of a post/thread in the body which makes me a bit unsure whether I'm trying to attach it the wrong way. With the faceplate attached to the shutter body, the screw hole doesn't seem to line up very well with the cutout when the dial is placed in the position corresponding to position of the lever inside of the shutter.

I flipped through ""Photographic Inter-Lens Shutters " but it had no mention of removing the mode dial when disassembling the shutter which also makes me wonder. If anything doesn't make sense, let me know and I'll try to be clearer. I'll be sure to give it a clean prior to assembling it fully.

Can you reinstall the cocking lever without replacing the front plate? Then you can study what happens as you move that lever here and there, etc.

The ones I have seen have a T/B/regular knob at 6 o'clock, not the B/reg dial yours seems to have. But the idea is the same, changing the interaction of the large lower lever that ends up at your B dial with the blade open/close lever just below the cocking spring mechanism (about 7 o'clock, 1 cm~ distance)- that slot is the key as I remember... been awhile.

Funny thing, I posted this link on a question at the large format forum

Hallo, ich möchte hier mal schreiben, wie man den "Dial-Set Compur" (der alte schwarze mit dem Zeitenrad oben) öffnet und reinigt. Meistens hängen ja nur die Langzeiten, wenn nichts defekt ist. Habe schon einige Dial-Set geöffnet und wieder gängig…

Thanks to to the both of you. Referencing the images on the german website I wonder if the screw might have broken off inside of the lower lever that seems to have a hole going through it in the pictures. The screw does seem to be quite short. Or is that something coming through from the bottom? Going off what is written, would I be correct in assuming that the selector pin on the dial should grab on to the cutout rather than the screw being screwed into it?

Yes.

Is it not possible to fasten the dial to the faceplate?
