    Its from Alpenhause. I really like his back. It holds very well, it's compact, it's light, and it will hold very thick holders easily. If I ever get around to it I plan on mounting similar springs on a Bender wood kit camera. the Bender springs leave a lot to be desired.

    You know what is amazing about that spring back is I have never had anyone complain or manage to ruin the springs.

    Here is one way to use straight spring wire. This is on a pinhole camera, so no focusing screen was needed. If used with a typical ground glass back, it might be stronger if the ends of the springs are mounted on the GG frame and the center of the spring bears against a screw on the camera body.
