Actually all the VO3x are no longer on perm 166 LONG AGO.
But according to SBS3107H he thinks it is just a
speculation.
I have also verified for you that SBS9628G has no longer been on
perm svc 166, the records will be reflected in SGWiki.
However, do observe which is the replacement wright for this
shift. Thanks!
9468B, it's former perm, has been appearing on 166.
