Vespa center stand

I'm just assembling my 1982 Vespa P200E after having it resprayed. My question is the return spring for the centre stand. I can see where it attaches to the stand, but does the other end go to the chassis or is there a bracket of some sort. I just can't remember. It's been in pieces for over 6 months which doesn't help! I took lots of photos to help in re-assembly, but not of the stand:(

Any help would be greatly appreciated, or if anyone has a pic they could send, even better.
