N/A Weihrauch hw44 trigger

[aroundlocks]

Hi all
I have a problem with a spring that looks like it came from the trigger section of my pistol but for the life of me I can not find where it has come from
Looking at the schematic it seems as if a pin holds it in place / part 10
Yet the spring fell out when I removed the trigger cassette as if it was just lose in the gun somehow.
I'm wondering if anyone has the info to where and how this spring goes back.
Any information greatly appreciated
Regards paul

The spring is not from the trigger sub-assembally.

It is part #13 which goes in the rear.
