Hi all - I've had this truss rod cover in one of my parts drawers for probably 20 years and I've never been able to figure out what it's off of. I got it on an old frankenstein Les Paul that had a 1965ish neck on a 1975ish body. It looks like the 1961 Les Paul cover but it's 3 ply. Any ideas? Thanks....
Mark.
