Charles Daly lever spring??

[herbnewsam]

I have a charles daly 20 ga. a customer droped by to get a new top lever return spring. I can find the hammer springs but not the other. It would be nice to have the broken one but his son lost it and I don't have a clue what it looks like or where it goes. I don't have nor can I find a schematic.
Any help would be great. thanks
