Significant differences remain between your picture of the guitar JR is playing at the mike and that of Larry's clarification photo. First in Larry's photo there are distinctive white marks to the left and right - these cannot be tricks of the light as there are no supporting shAdows to support the required angle of illumination. They are clearly some form of embossment not on the other guitar
Second in Larry's picture below the strings on the main body is the white line rim(jagged) followed by the white line or rim of the main body - there is vid tally no difference in spacing on yjese white lines where it sits on Jim's knee yet in your picture there is a clear spacing. Hence the photos show similar but different guitars.
