Cheers, as far as I know the original inspiration guitar on the first page of this thread is an Ibaneze 'Artcore' variant similar to this one.

I used Feast Watson stains, with 70%-50% diluted Brown teak and walnut that I airbrushed on for the burst, then Cabots satin poly. All available at the big green shed.
For a finish similar to that Harmony, I'd go and look at DarkMarks builds. He has his finger on the pulse of that style of guitar.
