The details I can see on your larger version translates to 10 September 1875 (the left hand side should have a 6 which isn't visible in the photos)... that would make it one of four designs registered by Sowerby & Co Ellison Glass Works Gateshead-on-Tyne. The design numbers were 294376 to 294379 294378 was a design for a bowl, 294379 was a dish and cover, the other two aren't explained.
