Model 'T' or THRIFT
The 'T' was made for a relatively short time in 1956.
They literally have an 'LX' handle (remnants?) and untilize the 30/XXX cloth Bag and have the 'full-sized' 535-watt motor.
While most came with a traditional Belden cord and plug (as did the E and AE and previous Electroli), it appears that other came equipped with a ribbed GE cord set.
