This page says you can identify the model based on the firmware
revision (which I don't think would change with your dip switch..).

My drive says (/proc/scsi/scsi)

Host: scsi1 Channel: 00 Id: 06 Lun: 00
  Vendor: ARCHIVE  Model: Python 04106-XXX Rev: 715G
  Type:   Sequential-Access                ANSI SCSI revision: 02

which I would interpret to be Scorpion as far as the above document is 
concerned, since the revision number is 715G.
