Hi Fretworn, my knowledge of 12 strings is very limited, but if I understand you correctly the nut was cut so the octave strings on the E,A,D and G were below the primary string instead of on top? Was there much difference in the grooves cut in the saddles or could you just swap the strings over and make do?

And while were on the subject, was the bridge hardtail or tremolo style?

Any chance of some photos? would really appreciate a look at it.
