This is some sort of screw-head holding screwdriver, but I would like to figure out the correct name and rough estimate of year that this is. If anyone could help that would be amazing. Thanks!(http://i50.photobucket.com/albums/f336/koodoofoodoo/IMG_1576_zpsebdb10ae.jpg)
Do you have a better picture of the working end? What is the purpose of the spring? I can't determine that from the picture.
