A friend of mine's father worked for Gibson when they were based in Michigan. He did the fine inlay work on the custom builds. My friend still has his dads tools plus 3 guitars that his dad built. I don't know if they still do or not but Gibson used to allow it's workers to build instruments for themselves. 2 of the guitars were built on the 335 and one on a Les Paul but he modified them a bit to his taste. Let's just say that the inlay work is unbelievable. The DoJ would go apeshit on these because of the woods used and because of the real ivory.
