Thank you Trev.
I checked the site myself but still left a bit puzzled.
I did not find a exact match with the hallmarks on my bonbonniere. Closest appeared the hallmarks regarding C. ( c.1854~1869 ) and perhaps also B. ( c.1853/J.C.Moore) but those appear too early years at least for me. I would more likely place my basket somewhere around the first decades of the 20th century.
And it is said on that site, that:" There are many variations in the maker's marks used by Tiffany & Co., the examples given are intended to give a basic guideline to the hollowware markings. A more complete listing of the mark variations can be found in Charles H. Carpenter's fine book, "Tiffany Silver"."
I do not have an access to that myself ( here in Finland ) , so I would be very grateful if someone who has the book could check my dilemma from there. If it is too much to asked, I do completely understand as well.
Best regards, Atlas.
