The Newport had a pickup cover that didn't actually cover a pickup. You can tell it's a Newport by the two knobs, and you can visually see that it's a shortscale.
It goes something like this:
Gibson EB-0 and Epiphone Newport - single neck humbucker, short scale
Gibson Thunderbird and Epiphone Embassy - two humbuckers, long scale, thinner (fragile) neck.
