Tag reads M65 3/4 5/3
S/n 116782
Hello Trb67,
Welcome! The model designation on the label probably reads: M65 3/4 SB. The instrument was made during the year 1975.
By that time the M-65 3/4 was actually no longer part of the Guild line, but your guitar is one of a relatively small number of leftover 'superstructures' that were still in stock and that were finished and completed.
Sincerely,
Hans Moust
