P.S. Your model list of spec's draws parallels to those of auto's. It seems that electric floor care companies such as Hoover and Eureka, mimicked auto manufacturers' trim packages by offering so many designs and options - especially since the Sixties. In turn, lettered model ID's and names resemble those of antique vehicles. However, since the floorcare cleaning companies haven't followed suit in publishing model spec's like the auto industry, details such as yours are valuable. Thanks again.
