Another round of our favourite game, "Name that Alembic!" ...
It is a set-neck bass with a mahogany body, so it can only have been ordered as an Epic or an Orion (a Rogue is always neck-through). Apart from the standard body shape, there isn't much to differentiate between those two, but seeing that the serial number includes the initials OW, it is undeniably an Orion. The custom options are the Rogue body shape (obviously), the Europe electronics (quite a popular custom option on Orions, and standard issue on a regular Rogue) and finally the bar tailpiece (again, standard issue on a regular Rogue). The inlay at the 12th fret may or may not have been done at the factory, no way to tell without the buildsheet.
