"Was it ever decided exactly how many were made? 30? 40?
I've got the gibson shipping records and they list 101 as the number shipped from 61-70. 33-61, 20-62, 10-63, 24-64, 12-65, and 2 in 67. I'm not sure but I believe the sg/ebo shaped body was only made in 61 and after that it was the eb2 shape. They do not list any in their 48-60 records or in their 71-79 records.
