Hi all,
Recently I acquired the cover shown below, posted in 1873 from Bathurst to Sydney.


Sawyer was an undertaker. The envelope was pinned to something in its time. One of the pin holes can be clearly seen at the bottom left of the front image.
What interests me is this handstamp, dated almost a year after posting.

I was looking through the National Archives papers I have saved and found a very similar marking on a document that was in the Katoomba Post Office files.

The full document is below.


Has anyone seen this marking before?
My best guess is it's a handstamp from the legal department of the NSW GPO.
