"Butterfly" mark on wine taster

[AllSeasons]

Well, I've never seen these marks on this wine taster dish, and I cannot for the life of me figure out which country/region these marks hail from. I even looked up the German, French, and Dutch town marks, but still couldn't find any matches. The number 2 next to the "butterfly" also baffles me; the closest I could find was the Kingdom of Holland system, where a "2" would denote 833 silver. Any insight into this would be appreciated.

Admins, please kindly move this to the correct forum as appropriate.

Hello, the marks remind me of marks on French plated items. Regards, Bahner
