ST HELENS "PAID" STEEL CDS WITH AN UNUSUAL DATELINE

[Ross Ewington]

In my quest to record late dates for the last of the steel datestamps used in Tasmania (see http://tps.org.au/bb/viewtopic.php?f=5&t=365#p1578)
I came across this unusual format of the PAID AT ST HELENS steel datestamp Type 5sT as per A&H. I would provisionally classify it as Type 5s(x)(T) - (X) denoting and
altered dateline in a non-standard format and (T) indicating that the datestamp had the time added to the original state of the cds.

In both examples, the year is in full - i.e. 2003 and 2005! Is this a unique variation of dateline format for a Type 5 steel datestamp? Can anyone supply
an earlier or later date of use?
