Washington And ? 1881

Hi all
Can anyone help with this?
Thank you

Washington and Washington. Both the stamp and the stamped envelope depict Washington. The envelope is Die 57 from the 1874 Plimpton contract. Scott number for the envelope is U163 which has 4 different possible watermarks and 5 different possible sizes. Impossible to determine size and watermark from the scan.

Perhaps a stamp expert will weigh in on the 3c Washington stamp which probably paid the additional postage for a double weight letter.

The Washington postage stamp appears to be the Scott 207 re-engraved design with the line under "TS" of cents.

207 was not issued until July 1881. I would say Scott 184.

Thanks everyone for your help
Much appreciated
