I used the head of a superfine dress-makers pin as a kind of hook to catch the springs and fed them back on to the contacts with the aid of a N0. 1 gauge British Standard left thumb. It took me two attempts to reassemble the mount to the back, (I got the sprung lever on the wrong side first time) but it works, reports aperture correctly, and meters fine. I can't believe I fixed it, WOOO HOOO.
Heart-valve bypass surgery, anyone?
