Very interested bass !
1: I had not seen Bookmatch to Center at that time (arround 80').
2: The horns and cutaway are not typical SSB, just like old small body (arround the serial No 25 to 40's).
3: The body edge radius is square like than others, just like as my Hyak.
4: 3 layered accent laminate is very rare at that time.
How about the serial number ?
Maybe it is on the fingerboard end.
Of course the bass is very nice one.
I think it is one of custom grade instruments.
