I know this is an old thread. However, I just bought a 1967 Gibson SJ from Rivington Guitars. The reason I bought it is because I used to have a 67 Gibson SJN/CW that I stupidly sold. And I am hoping to get another SJ/SJN as good. The 67 SJN was one of the best sounding acoustics I have ever had. I am commenting because my 67 SJN also had a 4 piece top. Mine was also marked with a "2", a second. I could find no flaw. It was in great condition. I have never seen another Gibson guitar with a 4 piece top and was interested to hear about yours.
