No issues, walnut, all original, tarbacks, Bigsby, Schallers, ebony board, small bump on bottom edge, case clasps, springs and hinges are all functioning properly. No smoke - pet - fragrance home.
My SG has a 6 digit serial number, starts with 134, which puts it in the early 70's based on body material, hardware, etc.
Please read the information on the first site, see the right side column in the middle that says: "The table below shows the years to which the numbers can relate." https://www.guitarinsite.nl/serienummers-gibson_eng.php
The following Gibson site shows they botched their serial numbers during this era and do not have any clear data which supports exact years. https://www.gibson.com/Support/Serial-Number-Search
