I wasn't able to find Hawkes items with that 83 Hawkes Sterling marking in the catalogs I reviewed. I did not notice 2-digit numbers in those catalogs. So it might be early or just not in catalogs in our collection.
I did find some references to colored glass and sterling mountings in the book, The Complete Cut & Engraved Glass of Corning by Sinclaire & Spillman. They discuss the blanks used during that time as well. Attached are the pages from the book.
I hope the information proves helpful. Let us know if you need further information. A photograph would be beneficial for further researching.
Thanks for contacting the Rakow Library.
