Help needed to identify possible date of French beaker

[Pope54321]

Hi

This beaker has recently come into my possession but I know nothing about it other than it's French. Any further information about date etc would be really appreciated. Thank you in advance! It is roughly 3 inches high.

Hi,
The maker should be Adolphe Boulenger - Paris.
Scroll down to his advertisement here:

Thank you for that.
Do I the marks give an indication of the date of manufacturer?

Hi,
Silver plating has already been rubbed off over decades of vigorous cleaning. Do not use any abrasive. Possibly warm water and soap then silver polishing cloth, nothing aggressive.
Protect it from elements (polluted air) to slow natural oxidation (a display cabinet will do).
Silver plating is rather thick and will survive us.

Thank you for getting back to me!
