Antique Central Scientific Twin Tycos Thermometers and Tube Barometer:
$103.50
Original TwinTycos thermometer set with barometer tube supplied by the Central Scientific Co. (CENCO). The instruments are in good complete condition and mounted on a 4 1/2\" x 8 1/2\" wooden wall plaque. Thermometers are intact and operating but I can\'t vouch for their accuracy. Barometer tube is in excellent un broken condition. This will need cleaning. Has been stored away for years
