mystery letters on Gorham sterling holloware

[naina1st]

Dear member,

Please have a look at the plate with Gorham mark.

There is also the dale letter
(looks like I for 1876 - not sure). The mystery is in the presence of letters DGF at 90 degree to the word sterling.
I cherish hopes that somebody knows what do those letters mean?
Thanks for everybody who renders help.

Hi Tatiana,

Dear Trev,

Thanks for your posting. You moved me to the right direction.

I saw the article by "The Owl at the Bridge" but missed the part regarding letter system for specials introduced in 1898. I was blinded dating the platter from 1876 with letter "I".

Now I have recovered my sight to notice the letter "I" looks more likely as number "1", and the platter is missing the cover (probably marked with number "2").

Bow low.
Tatiana
