Help Please Identifying SIlver Bowl and Marks

I have what appears to be an early ornate silver fruit or nut bowl with marks “IW” and “19” or “13.”

I’d greatly appreciate any help identifying the possible era, country of origin and meaning of the hallmarks. My own research (internet and Tardy) hasn’t worked.

Many thanks.
