Broken torsion spring

We have an 82-400 in our patio door. It has been in service for a long time and still looks good and works well except for one thing. There is a little torsion spring wrapped around a screw in the lower inside corner of the case. Wire diameter about 0.030", 10 turns, left-hand wind, 3/16" OD, 5/16" straight extensions at 90 degree orientation. This is the spring that pushes the latch bolt out.

is there any chance you could send me one of these? It's worth $10.00 to me. I can't find a spring quite like it anywhere on the Internet.

Thanks,

Tom
