This listing is for a Vintage 1921? Cenco Meter Testing Rheostat, with 18 Knife Switches, made of Wood, Brass & Copper.There is no model number on it, but the 1921 EMF Electrical Year Book lists Central Scientific as a maker of "Rheostats, Meter-Testing" which "...usually consist of a number of single-pole knife switches, each controlling a step of resistance."Further research shows that nothing like this is present in Cenco's 1932 catalog, so while we can't guarantee that this dates from exactly 1921, we're pretty confident that it's in the right ballpark.It is in good condition for its believed age. The varnish has mostly flaked off and there's some curving of the lid. A couple of the resistors look to have gone open circuit. We tested a couple of others - the 9.2 read 9.2 on our DMM and the 94 read 93.7. Some wires have come loose, both bus wires underneath and at least one resistance wire, on top - see last pic. Sold as a collectible with no guarantee of functionality.This is the only one on - don't let it get away!
