<p>[QUOTE=&quot;Jon N., post: 399433, member: 8521&quot;]Thanks for the suggestions.&nbsp; I took the galvanized metal strap off so I could see the markings around the perimeter of the bottom.&nbsp; The clear ones read:&nbsp; &quot;2-CP&quot;, &quot;J-3794&quot;, &quot;NSS CO&quot; .&nbsp;&nbsp; The markings where the leather straps connect at the front are a bit harder to see, but I think one says &quot;WALNUT&quot;, and the other starts with the numeral 2 plus a couple more characters I can&#039;t make out-&quot;2??&quot;</p><p><br /></p><p>I began googling those markings but no luck yet.&nbsp; I was hoping to find it had some therapeutic use. </p><p><br /></p><p>The leather straps and electrodes appear to be original to the chair. The metal strap and the wiring appear to be added later, perhaps a DIY project?&nbsp; The suggestion that it was a heating system came to my mind when I first saw it, but I&#039;m not convinced...&nbsp; I&#039;m no electrician, but it seems that if you ran enough current through it, the parts that would get hot first would be the parts with the most resistance.&nbsp; Since the wires and the electrodes are both copper, it seems the smaller wires would get hot first instead of the larger electrodes.&nbsp; I guess that would provide some heat to the seat area, but would also be a tremendous shock and fire hazard.[/QUOTE]</p><p><br /></p>
