I checked the truss rods, no Allen heads to be found and they do look like 5/16" nuts the forum will not let me post more pictures but would have no problem sending them to you if you really wanna see them. The serial numbers on the stickers match the headstock serial numbers and both numbers come back as Bozeman, Montana made guitars. The original owner of these guitars was killed in a car accident, and I bought them from his brother in law who doesn't play acoustic guitar and wanted them to go to a good home. I was given copy's of the receipt for the J45 Rosewood, as well as Gibson owners manual pamphlet and warranty pamphlet, and a pre-packaging checklist. The mystery model had no paperwork or anything, but he did give me a packet on the electronics. He also told me if I was unhappy with them or if they were found to be fake, to let him know and he would give me my money back. I paid $800 for the pair with hardshell cases. I have an appointment to bring them to guitar center and get them looked at, just trying to learn as much as possible before hand.
