Need Help Identifying ~ Two-Sided Tax Stamps? (Front & Back)

The blue side is the revenue stamp. The black side is called a cypher, it has the insignia of the king or queen who was reigning at the time. There is a lead staple holding them together that you can see from the front.

revcollector... thank you kindly... any idea of country and time period?

It looks like it's from the United Kingdom aka Great Britain and under the reign of King George.

Thank you, jogil... I have an old Scott 3-book A-Z set (1983)... it doesn't appear to have either United Kingdom, or England or Great Britain for some reason... unless there's some other way to look it up... ?

I believe thats' called an escutcheon, or at least the method of attaching the stamp to the document is.
Here's a partial response to this question from an other forum

'Escutcheoning" was a method to ensure that revenue
stamps did not detach from vellum / parchment documents.

The embossed revenue stamps were on a seperate
piece of paper from the document. They were slit
twice with an escutcheoning knife and a (metal) band
passed through the two slits in the stamp (and the
parchment of course).

On the reverse side the ends of the band were folded
to secure it and they were then tied to the back of the
document with a paper seal bearing the monarch's insignia.

I believe the band was also known as an escutcheon.
The document front would look like this.'

Thank you, James... those links aren't coming up right now, I'll try later...

Don't worry about the links Disi.
The original posts noted that they may no longer be available, so I wouldn't bother. I guess I should have deleted those parts.

Some idiot snipped me on this! you bet I'm mad.
