American Electrolux was always somewhat ahead of Canadian Electrolux in the innovation department, but this seems to be a case where the opposite is true. The telescopic wand may not have stayed around for a long time, but it must be the basis for the plastic sheath/steel wand that became standard. After all, didn't the early version of the 1205 (out around the same time as the 89) still have the Model F/G style power nozzle with long plastic wand and hose cord?
I suppose the same is true of the dark green electric hose with direct connect pistol grip handle for the 89. When did American hoses adapt the direct connect handle? The Canadian electric hose seems to have come out in 1968/9, or around that.
I'm constantly fascinated by these details, and how American and Canadian Electrolux vacuums of that period converge in design, style, and attachments.
