SSB is Short Scale Bass, SSG is Short Scale Guitar.
I pointed out about Alembic logo.
Oldest logos are unknown, I only know 72-01 has no logo ?, 72-02 has shell inlaied cloud.
Older inlay logo as folating A : A is floating in the circle. (72-10 to 73-43 on my archives)
Newer inlay logo as gripped A : a hand grips A with circle. (73-47 to 74-52)
Then the gripped A logo was mounted on a head veneer. (74-53 to 77-720 or 744 ?)
Current logo is detailed cast silver inlay (77-755 to now)
This bass has gripped A inlay logo.
So only 3 basses (73-44, 45, 46) are match in this case.
