This, folks, is the original Kirby Heritage 1HD power cord (#192081) with the 1967-style shaped male plug (with the 1953 Kirby circle logo) on it, which dates back to the Dual Sanitronic 80. Prior to '67 or mid-'66 the cord was actually all curvy including the front side with the Kirby circle logo.
There was also another version of the cord that has a different shaped male end (more angular than this one) which has the Kirby script logo (sans circle) running vertically.
The female end of the plug was changed at some point late in 1982 (this one is still slim), since they changed the cord socket on the motor switch.
