This is a truss rod cover with the "玲" logo that was previously installed on a 2000 Gibson Les Paul Standard I purchased used. The details are unknown, but I think it's perfect for a Tak Matsumoto fan. I was able to install it on another Les Paul Classic I own, so it seems to have high versatility, but I don't know if the size will fit other models like Epiphone or DC. There are no screws, just the cover. Thank you. Search terms: Gibson Tak Matsumoto Takahiro Matsumoto F.A.T indigo note
