Grant Letter Sheet (Scott U293)?

What's the Scott Number for this item?
It says 1879 on the reverse.
I can't find it in my Scott Specialized.


***Title Updated by Mod***

The Scott Specialized combines the embossed envelopes, wrappers (and letter sheets together). Look at U293.

Add: The 1879 date refers to U.S. Patent 217,155 issued on July 1, 1879 to Lebbeus H. Rogers of New York City for his "Combined Envelope and Letter-Sheet". Here is the illustration page of that patent. The descriptive claims fill another page and a half of details. It took a few years for the USPOD to decide to produce these.

Thanks.
Once I got to the listing I saw the image (don't know why I missed it previously).
Now I have to count the perfs to see what variety I've got.

Biblical Names Meaning:
In Biblical Names the meaning of the name Lebbeus is: A man of heart; praising; confessing

Would the moderator consider correcting the title to indicate that the thread is about the Grant Letter sheet (Scott U293). It would make this thread easier to locate with a search.
