I forget if Antoria was knockoff of Harmony, or a knockoff of Kay... but anyway.
how on earth and open string and then first fret can be that out is beyond me
This definitely sounds like the nut is in the 'wrong place.' If the first-fretted note is higher than it should be, then the strings may be too high at the nut. If they're not too high, then you can take the nut off and cut the end of the fretboard so you can place the nut closer to the first fret. (this doesn't have a 'zero fret' next to the nut, does it? If so, you may have to pull it and put the nut in that approximate location).
Go ahead and hack on it, it sounds like you can't make it any worse. Do you have a strobe tuner? That can help with these things.
Worst case, do you have a fireplace?
