To be a proper Black Beauty, the guitar would need an all-mahogany body, no maple cap.
It'd balance out the tone a little better with the ebony fretboard if built that way, too (just my opinion).
On the other hand, you'd need the cream plastic body binding, the pick guard, and all the other Gibson effluvia, so might as well just get the Gibson version; they're still making overpriced reissues of them.
