I've found yet another Scott-unlisted test (or dummy) stamp.

This is now listed as Scott TD30.http://goscf.com/t/59276
Not yet listed in Scott.
The "new" test stamp is intricately engraved with a beautifully nuanced, artistic design that-- oh, wait a minute, my bad.
Maybe the opposite of that. Maybe "utilitarian" comes to mind. See below.
This is, as far as I can tell, only the second known copy of this stamp. The other one can be found pictured here:https://sites.google.com/site/gbsta...sting-labels
The stamp is perforated 8 1/2 horizontally, and it was used around 1910.
Here are also some advertisements for the machine that used these stamps. Both were found in 1910- to 1912-era magazines.
Maybe Scott will list this new one in their Specialized Catalogue one day.
