I've got an old 4001, and have always wondered "what is this paint squiggle on the back of the headstock?"
As you can see, it's as though someone used a fine point ink marker (or paint marker) to 'write' something on the back of the headstock
But it's UNDER the finish, and I think that the finish is original
So......I don't know what to make of it. Have any of you seen anything comparable?
Or have any thoughts?
thx much -
Richard
