Dating a Limoges Box

Looking for any insight on this Limoges box. About 4" tall and 3.5" wide. My Gma gave me a Limoges trinket box every Christmas. This one was in her collection. Needless to say she was a fan, but I was too young (read: ignorant and self-absorbed) to ask much about it when she was alive. Ahh life. I've scoured the internet and can't find anything definitive. Appreciate any info, thank you!

 

HERE is a plate with a very similar mark, though of a different pattern. The seller doesn't offer a date. THIS website states it is an unknown Limoges maker but again doesn't offer a date (third row down, fifth example). My suspicion is mid-20th century but granted, this is not an area of expertise for me. We'll see what others say.
Pretty box!

 

Amazing - I appreciate the help! I've found the makers mark in a few online catalogs like the one you shared, and similarly, it's always unknown. Seeing other examples/patterns like the eBay listing helps. Thank you!
