Hi there, I've got an eye on a beautiful 60's SG Junior, but the seller is not 100% of the year it was made. I've got some pics and a serial number so I'd appreciate if anyone could help on this one! He also says the nut width is 1 9/16 which I believe must be post-1965, but the pots (that may have been changed for some reason) are dated from 1961 (number 134 61 20). Serial number is 26812. Cheers!
