A contemporary continental mark, but would be grateful for any help with origins please.

Hello, maybe I can help:
925 marks for silver purity;
polygon with star/number/province is the trade mark of the manufacturer in Italy.

Excellent. Thanks - a good start.
There’s a thread here that I’ve found
925-1000.com/forum/viewtopic … 38&t=27003
Many thanks
John

If anyone is interested, I think I have subsequently researched these maker’s marks as: -
FLORENCE OF BUSSOTTI PAOLO E C. SNC in the Chianti region with the ‘F I’ meaning from 27/02/1992 (I think!)
