I'll assume you're talking about a koa top with cocobolo back and sides, and a koa neck. The fretboard and bridge could also be cocobolo. That, along with the species and arrangement of the bracing, the size and shape of the guitar, and the intentions of the builder might be enough to may an educated guess.
Without at least that much information, it's just a WAG, and yours is as good as anyones.
