No, wait, that can't be right. They don't reach that number till 1991, but as you say, they're well into the "J23" prefix by then.
Oh, interesting.
I see what you mean, actual JF30's were only up to 618 by the end of '88.
Now suspect maybe they actually started a higher s/n sequence for the 30-12's before converting to the J23 sequence?
Also, remember those numbers are the
last ones in the given year, sequence changes
during a year, which is when they usually seem to have happened, have often led to the impression of missing numbers.
So if they only used that JF30 prefix on 'em for a limited period in '87 or even into early '88 before switching to the "J23" system, they'll never show up.
Recently seem to recall some outright bad s/n's on the site compared to actual input from Hans, so there's that possibility that the JF3012 numbers never actually existed, except a similar foofaraw of changes accompany the JF50/JF50-12 and JF55 and JF65 and even JF65R numbers: JF65R0019's a 6-string, JF65R120018's a 12.
Then apparently they spent a couple of years in agonizing indecision about whether to re-instate the time-honored F512 model name or submit to the tyranny of the new system and rename the JF65R12 the JF55-12.
Hey, you were a lawyer, this should all be second nature to you, right?
