Partial stamp, possibly apothecary??

[Masoncie]

Hi. Any help with the marks on the base would be greatly appreciated. As only partial stamps visable I'm not sure where to start!
It feels like silver as the lid is very thin and flexible, but as no visable assay marks I thought it best to ask here.
My first thoughts were apothecary as one of the marks looks a little bit like the top right corner of an apothecary symbol.
8"1/2 high including the lid. Thank you.

it is French silverplate: doublè.Below an example

This can narrow your search.
Good luck
