St. Silver maker mark

Hi Everyone,

I’m hoping for some help to identify this mark. Im pretty certain I have found other items with a clear mark.

First 2 photos are the ink pots? (Guessing)

The next is what I believe is the same mark on a letter rack, with link.

Then is a Catwiki listing for weird miniature goblets? I think is the same mark.

I may bid on these and was hoping to find out beforehand, so I have an idea.

Thank you for looking.

 

I’m assuming the St. silver is worn. Maybe they are ink pots, but I’m not certain. The lids are threaded.
