compur shutter unknown parts

hi,

need help here guys (girls) in the attempt ( more of a iddle day efffect actually) to see what is going on with my 18cm 4.5 voigtlander in compur shutter which only fires in one speed (B and T working good) i decided to open it up.
so i open the upper part and got to this view



then i open the plate thst covers the gears etc, and fire the shutter, alas this thing jumps out


this is the condition right now


i dont know where it came from and its function, so if anyone here is experienced o this shutters could point me where to put it?

cheers,

Dave

I'm thinking that piece is a bridge that locates the pivots of the gears visible at 8 to 9 o'clock.

that's what i think also, but i have no idea where does it sit i've emailed sk grimes about sending it, but have not yet receive reply.

Well, if you'll notice, the holes for the pivots are two different sizes. So there are only two possible orientations. The real question is: why is it loose?

right! well my guess is there is something missing here, this lens came with the camera i bought, already in this state, so i just figured what the heck and open it up, and there's is also the possibility that the part is already loose before i open it
