Copper Eagle Stamp, U.S. Gov./ Mil. origin?

I recently acquired a copper eagle stamp, with the eagle clutching arrows, made with a pass through in it to set type, numbers or names in the stamp (I think?) I do not know its age nor original origin, but it is well engraved, with fine detailing. I can find no markings. The walnut or mahogany block has ink staining, the darkest where one's fingers would be placed. I did clean dried ink off the stamp with a toothbrush, it is otherwise as found. I am new to this forum and I sincerely appreciate any information. I haven't seen another like it. It measures 3 3/8" long x 1 3/8" tall x 1" thick. The engraved copper plate is approximately 3/16" thick. Thanks in advance to anyone who can help.

It looks more like metal type casting than engraving, and in the old copper-plate type script. I agree that the "window" would be for the addition of information that changes from use to use - like serial numbers. It is for relief printing but might have been applied to any number of different papers/forms/certificates.

 

Agree with your analysis as to use. Think it is at least mid-19th century, though could be older. Stylistically, could be as old as the late 18th century.

 

Thank you for your reply. I was wondering as to the origins of the Eagle motif, if it was a known U.S. Postal, military, or other Governmental insignia that was used, the insignia of a known Company or Corporation, or if it was just a random letterhead. The copper may have been cast, but it was then hand tooled and detail was later added, as there are details that are far too fine to be cast, particularly to the top left of the scroll, perhaps not evident in the photo, they are as fine as any plate lines in U.S. currency.

 

I suspect Gov't or military use would necessitate the proper markings on the reverse ..

 

Don't think this governmental. The eagle device was a popular motif used by everyone in print.

 

just because ...
