If it has eight tubes, four bands, and a horizontal mounting power transformer, it is a model 650.
If it has seven tubes, four bands, and a vertical mounting power transformer, it is a model 640.
The 640B and 650B used identical tombstone cabinets.
And the oddball band switch is correct for the 650. At least, it is for at least some of its production run.
