Italian silver bird placecard holders - help please!

Need help identifying!

Have a set of 12 of these, we inherited from my wife’s grandmother in Switzerland. From what I’ve read online, they’re Italian, post-1968 800 silver from Milan.

Best I can tell the makers mark says 904? They all have the 800 stamp as well as

* 904 MI

Any help identifying is appreciated!!
