First time to the site hope someone can help. I took this RG721RW premium as a trade for my Les Paul studio a few years ago but have had no need to adjust the truss rod until now. I opened the cover today and there is no nut or hex bolt. Has anyone seen this before? Not sure if it's broken or a factory defect or what. Here are some pics. Am I missing something here? Thanks in advance for any help.
