Steering column question

So I am putting together a 71 floor shift steering column that's been completely been taken apart and I am wondering what makes the key release lever spring back? (it must right?... can't be manual both ways?)

You know the collar that has the little decal that says "To remove key - depress lever & turn key" on it

Owner swears all the parts were in the box but the 71 parts catalog shows a spring & bumper for 71 floor shift column I suspect this my answer....

Anyone have pics?
