Help identify this maker’s mark please

Has anyone ever seen this maker’s mark before (the first one from left)? It’s an Italian piece made after 1968, it has the rectangle with pointed sides, star symbol on the left and number 17 I think, the rest of it cannot read. Any information would be greatly appreciated.

Try cleaning the mark. The letters after “17” are key to an identification.


800 = 80% silver content

the image appears to be of something used for a bonbonniere (wedding gift)
