Levelofmadnes, it might be WDDO-006. Try matching the die markers for WDDO-006.
Here's a 2012 WDDO-004 that was correctly identified after a second Acetone soak. The die marker in the "G" of "GOD" in "IGWT" is visable, but it was hard to see in my photos. http://goccf.com/t/327832
Yup, the WDDO-004 die marker by the G was there. Maybe a coincidence. But the die marker under N in ONE for WDDO-006 was also there. Some of the die markers were not present for WDDO-004. If WDDO-004 had thickness in IGWT, I would only have the date to go by.
