Might wanna have a look.

Not sure of the originals, but Akira's are now made under the Killer logo, though I do think ESP is the actual maker.
And Killer-branded Akira originals (the red with the metal plates and Dano head) are *always* back-ordered.
Your customer may have a winner.
If I'm reading the catalog scan right, the original price was 11,000 Yen, roughly comparable to $1100 USD. Take off the neck and see what's under the heel.
