Time Period Manufactured Pre-1930

Check the listing for details. Antique CENCO Extended Coil Type No. 10436 Wheatstone Bridge. Listed at 150.00 USD. Antique Central Scientific Co. slide wire Wheatstone Bridge extended coil type. Developed at the University of Illinois to be used for conductivity measurements. Bridge is of the usual slide wire form with half meter scale graduated on top half from 475 to 525 cm, and lower from 0 to 50 cm. Extra coil is wound on spools, and on this model placed on bottom of device. The only catalog examples I found were still placing the extra coil on the side of the device, so this must have been an upgraded version. This model could be used as either a half-meter or a ten-meter bridge.
