From my forthcoming book, "Rickenbacker Basses - 50+ Years As Rock's Bottom":
"Production. First announced on the official price list dated December 15, 1995, the new limited-edition bass retailed for $2429. No mention was made on the list of the number to be produced. An edition for 50 was planned, but this was later increased to 60 to fulfill orders. Although a two-pickup prototype was shown shortly after the announcement, it appears that early production Lemmy basses weren’t issued until early in 2001.
The January 1, 1998 price list showed the Lemmy retailing for $2799, but it was missing from the January 2000 price list. It reappeared on the January 2001 list, again at $2799."
It is likely that a few trickled out in the late 1990s, but I have not seen evidence of that (listed by date codes on jackplates).
