Hi. Looking for help to identify this small cast openwork dish. It is just 9cm long, 7cm wide and 4cm high. Heavy gauge silver. It is marked with:
1: N in a circular or oval punch.
2: IR in a circular punch
3: A mark which I think is an Austria Hungarian Import mark for 1872 - 1901. Strangley this small mark appears to be stamped inside a bigger stamp which I cannot make out.
Could the dish be from Nurnberg or more likely Hanau...... or somewhere else? Any information much appreciated. Many thanks.
