Antique #21139 Jaquet Polygraph Machine Lie Detector Swiss Science Instrument

Description

Here we have an antique #21139 Jaquet polygraph machine, or lie detector. Item is made in Switzerland. Nice vintage scientific instrument. Looks to be in overall good condition for its age. On one of the two bundles of orangish plastic tubing, the plastic is cracking, so i have not tried to unwind it to prevent further damage. Can provide photos of this on demand. Item is, of course, untested. Please look over the photos for yourself to see exactly what it is you are recieving. Don't hesitate to ask questions.
