The link to the listing was correct but the seller ended auction early (either he sold them or there was indeed an error in the description, so most likely Ibpesq was right and these were not Alembic Pups).
Yes, I did wanted them for my Guild...
tbrannon's observations on the bass are correct. The starting bid was $225.
It is not a pup selector Jack, just the logo plate.
I intend to restore this bass if possible and will certainly need all the help and advise I can get at this Forum (Mica included). Guess that deserves it's own different thread...
