Yes that is the slot that the end of the mainspring engages with.

That right gary the spring anchors at that point, the arbour when  fitted winds in the direction to maintain the anchor point.  I will do the pics tonight for you.     V

Yes, that is what the spindle anchors to, all of the spindle rests behind it.

You should keep an eye on the spindle as you lower the MS down inside,  it breaks off  easy.

Hi Gary Photos as promised...      They all detail how the spring fits to the barrel wall and to the arbour.  If you are fitting it by hand wear some latex gloves so as not to get fingerprint and moisture on the spring. Cleaner the better     Hope this clarifies the method.

     winding by  hand  (thumbs);   does not work well with gloves on.  vin

Hey mine appears different Pic 1 sorry not clear has a small button on it as does pic 2.

3 and 4 show reverse side with just a slim piece of metal over lapped.

Thats the best my phone or meself can do with pics.

Does the button go against barrel wall (which i think it has to) or the slim over lapped other side. (which would then make it impossible to attach the arbour).

cheers

Hi Gary  find attaches the pics.  The problem with your spring is the rivited attachment on the outer end has broken off leaving the rivit stump and nothing to attach to the barrel  see pic 3316 and 3313 enlarged. Without this attachment the spring will not hold on the barrel wall notch 3312. in short the spring is knackered and needs replacing.
