Probably not. My bass was made during the transition period, and Roger said he couldn't tell me from the serial...
That's surprising. My bass was made in 1986, and when I bought it last month Roger looked at his build log and told me all about it.
Try tapping on various areas of the top. If it sounds hollow it probably is. I used to play Alembic Series basses, which are usually semihollow, and which was apparent when you knocked gently on the top.
