Hi Kendall; and welcome. This discussion group is monitored by Alembic staff, monitored to the extent that their work load allows. So this is the right place to post the serial number; and if one of the Alembic folks happens to see it, they will post the information they have on your guitar. By the way, we don't see too many Series I guitars; so if you don't mind, the group would love to see some pictures.
