I'm not sure when I bought it, but I'm selling the neck because I changed instruments and no longer use it. The box says A901, but the neck says #92 GP (Correction: It was #192, see the 10th photo of the reference catalog). It's the type with engravings. This is a personal item, so no claims are accepted. It's an upper type, so if you're replacing it, I recommend having a music store adjust the neck. Thank you.
