I noticed that too, Fred, when I was attempting to splice that ad back together, and in other Big Wheel ads. Let us say the Creative Advertisement Department was overstepping their mandate a tad using two hoses and a long lens to create those shots. "Truthiness in Advertising".
The cloth woven portion of my Model 77 does measure 6.5 feet and the Model 105's vinyl hose is 6 feet between connector and handle.
8 to 10 feet would be so much more practical and useful on any pull-around or swiveltop vacuum cleaner, as Hoover did with the Ultraflex on the Constellation. The standard Variflex hose with my Model 51 cylinder (and the Junior 115 upright) is a full snaky 7 feet between connector and handle.
