The vibromutes don't yet have the Mosrite logo. You'll also notice on the back of "WDR Vol. 2", that came out a few months after this, a close-up of Nokie's Mosrite where the angle of the fretboard at the base of the neck is not yet cut to match the angle of the neck pick-up.

You can see the neck heel / neck pickup angle mismatch in the picture above, too. What I find so interesting is that I've never seen another Joe Maphis / Ventures guitar from this era without binding. The student guitar with one pickup and a smaller body didn't have binding. So while these were prototypes, it seems like Semie would have had to go out of his way to make a sidejack with no body or neck binding.
If this guitar still exists somewhere, it will be pretty easy to identify as I doubt there are any others like it!
