Gary--It's interesting to see the little design changes in those Oster pots over the years--spout, lid knob, etc. I have both the solid Avocado and the see-through Harvest Gold models. Currently using the HG one as my daily driver.
Now, my avocado one came with a special Oster-branded white cord. I really like it, as the standard black cord is so ugly. When I tried to use it with the HG one, it didn't fit i to the "hole" as well.
(Okay, I'm really opening myself up here...)
I could force it in, but it was a really tight fit and I usually ended up with some sparks.
There. Done.
Anyhoo... the standard black plug works with the HG Oster, so go fig.
Love that Universal of yours! From the first couple of pictures, I though it was from the '30s. How surprising to find it's a much newer model.
