All TB Plus versions are the same style, blades instead of polepieces and ceramic magnets below. They may be wound to the same general specs, I don't know. Even so, they would have to have identical bobbins underneath the covers and be spaced the same to be considered the same.
I haven't had the opportunity to measure any bobbins or take any readings, buy we know for sure that the TB Plus in the SG RI (neck) has two widely spaced bobbins; the spacing would definitely change the sound compared two bobbins right together.
I've never heard an Orville or seen the insides of its pickups.
