Help with identifying another hallmark please

This hallmark is the only identification on the back of a large heavy tray I picked up at a rummage sale. Almost positive it’s plated but can’t find any information on the maker. Please let me know if you know who the maker might be. Thanks for any help with this or the other post I have out there.

This has been identified, although not with certainty, as a mark of Concord Silversmiths; it has also been suggested that it could be Continental Silver Co. Both of these companies are American so if your tray were silver it would be marked “sterling”.

Thank you Phil. I’ve heard of Continental but not Concord. If you ever get a chance, I have another post out there regarding a pattern name and possible age. Any help is appreciated. I’m so glad I found this forum. Thanks again.
