The 3D photos below have not been  made with my Stereo Realist stereoscopic camera, but by sequentially taking two pictures with my digital snapshot camera (laterally displaced ≈ 6.3 cm (2½") between the left & right shot). I have converted the stereo-pair photos into red/green anaglyphic 3D images, with StereoMaker (freeware). You'll need red/green glasses to view them (the close-up of the printer mechanism really came out great, even if I say so myself).  I have made hundreds of stereoscopic photos over the years; a small selection is on my stereoscopic / 3D page.

I am not aware of the existence of any other 3D photos (historical or new, like mine) of Hellschreibers. If you know of any, please let me know.

FELD-HELL

The Amplifier and Interconnect Unit

This is what's inside the gearbox of the Feld-Hell machine. Pin-coupling to the motor-generator is at the top. Large gear (top right) connects to the character drum.

To take these photos, I had to suspend the shafts by marionette-strings (monofilament fishing line); see the jig below.
