For Macro Mondays "Numbers" theme. A mechanical integrator is a complex device that was used to calculate ship's stability before digital computers became practical. The complete device is similar to this image: commons.wikimedia.org/wiki/File:Mechanical_integrator_CHM...
The lens used was an old manual Zuiko 80mm f/4 macro on a sliding extension tube and micro 4/3's adapter, in spite of what the exif info states. Four Olympus high res shots were stacked in Photoshop. I would of liked to gotten one more but ran of focus adjustment.
