Two items, first one is a cake or pie server, see images below. Further up the back handle it says H. Mahler (Just H. Mahler, no Sons). Unsure if this is one of his designs or it is just marked such because he was the company selling it.
Second item is a large serving spoon, have NO idea about the hallmark. also reads “Sterling” and “Copyrighted” and “R. Harris & Co” but I believe the R. Harris and Co is just the company selling it.
Any help appreciated!! Pictures are added as attachments.
