Silver double sided ladle with "B + train/engine" hallmark

[MiB]

Hi, I have this ladle from France. There is only one hallmark. Can I ask to help me to trace the origin of the item and decipher the hallmark? Thank you.

Absolutely smashing. Thank you both.
My ladle does not have digits "90" as per link. Does it matter?
