“1847” is part of a trademark used by this branch of the Rogers Bros companies. You will see that the IS mark of International Silver is also included here so that puts your tray into the 20th century and, judging from the lack of wear on the marks I would suggest mid to late 20th century. However, as it’s so difficult to date electroplate, that is just an educated guess.
