The weird thing is, that toaster looks like one I brought to the Long Beach wash-in as a give-away item. I think Fred may have taken it. If it works the same, that lever actually flips open the center portion of the toaster 90 degrees, with the top surface becoming vertical and the side surface horizontal, revealing guides for two slices of bread. Place the bread inside the guides and flip back over to close and toast. Heating element was manually controlled by an in-line switch.
I don't know if the bread gets toasted sideways or if you place the bread into the guides sideways so it toasts right side up. The whole thing didn't seem practical and I never used it, so that's why I let it go.
Again, if it's like my toaster was, you wouldn't be able to use the burner on the right because you'd need that space for the bread holder to flip up and over for loading and unloading.
