Found out something interesting the other day.
I always thought Korina Flying V's, etc. were made out of Korina WOOD. I was informed by a friend at my local amp shop that the original 50s Vs and Explorers were made of WHITE LIMBA WOOD, and the FINISH was called Korina.
Learn something new every day. Korina is the name Gibson gave to the finish.

According to the above, it is not rare or endangered.
I do like the color. And my Epi Korina V has a distinct mid-rangey sort of "bark" to it.
Something I have been meaning to do for years, but have never got around to it, is get Seymour Duncan PAF clones to put in it, along with actual Gibson electronics.
