Glad I could help. I'm pretty sure the Standard variant was around during the time of the model K as a lower end model, but I could be wrong. The fact that the vac has click connections instead of one long cord leading to the terminals means that it is a bit newer. The one on mine has the same thing, making shipping much easier. Below is my later 10 and my early 10 parts machine with different wiring in the handle.
While we used vintage cloth wire, in hindsight, we should have picked up the brass old school connectors, too, nice yellow, right?? And I don't know why the writing on the bag looks pixelated.
