Help assembling a Seiko Skyliner

[paulskiogorki]

Hello.

I have been given a Seiko Skyliner in pieces and I'm trying to reassemble. I haven't been able to find a service guide for this movement (402, which I understand is same as 6222), so I've been following this video -

Unfortunately the part I'm challenged with is not addressed in the video. In the screenshot attached I've circled the problem part in red. I believe this is a ratchet that prevents the barrel from unwinding? I mounted the part as seen in the video but it just spins out of the way and lets the barrel unwind. I have another part that I can't account for, a small wire part shaped a bit like a question mark. I can't find another place for this part, but also can sort out how it might mount below that ratchet.

Thoughts?

I haven't worked on a Seiko but I'm guessing it's a click spring.

The click spring Richard mentioned is mounted below that ratchet.

The part you have circled in red is the click which locks into the teeth of the ratchet wheel...which you don't have in place...to stop it from unwinding the power that you provide to the mainspring inside of the barrel at this end of the train ( you wind power in ...it instantly releases that power back to the crown winder if the click is non functional )  The ratchet wheel sits on top of the square profile of the barrel arbor to make connection with the mainspring....from this power is provided to the mainspring via the crown/windingworks/crown wheel/ratchet wheel connection when you wind up the watch. If the click spring....shepherd's crook....is not in place correctly...the click will not return to lock back into the rathet wheel teeth to stop it all from unwinding. 

The click spring fits under the click in a way that makes the click return back to lock its single tooth into the ratchet wheel teeth to prevent it from unwinding. The click acts as a one way power storage lever...it helps to keep the power going forward.

Correct English sentence wording " moving forward "

Could you post a photo of the spring and the barrel bridge with the click and the ratchet wheel removed?

Thanks for all the replies. 
Here is a photo as requested by most recent reply.  I can’t quite work out how to orient the click spring under the ratchet. If you can’t see in the pic, the spring has a little hook on the end of it.

If you look on the curved end of the spring it has a little down turned bit on it, it goes in the hole in the plate

Spring don't look right matey, the spring needs to latch in/on with both the click and the plate.

Spring is correct and think it's the correct way up now to sit under the click.
