Although the Sevres marks are slightly different, these are a matching pair as the Registration marks match 412412 (very old Victorian items had registration numbers). gravy boat says ROYAL SEMI PORCELAIN and saucer SEMI PORCELAIN. There are dark marks here and there but they are fired into the porcelain. Both about 8 inches long. Sorry there is no pattern name.
