I believe this is a rare type, decorated with turquoise. The wood appears to be rosewood. It has a considerable thickness and is chamfered, giving it a very luxurious and satisfying feel. I think it's a rare item that you don't see anymore. The distance from the bottom edge to the hole is approximately 43mm. There's a slight chip or imperfection on the upper left side, but it was there from the time of purchase. I used to have it on a CE, which had a natural-colored head, but it was barely noticeable when attached. It would be even less noticeable on a core model or SE, which are darker in color. Available for immediate purchase. Thank you.
