A pretty set of 12 early c.20th coffee spoons with a nice reed & ribbon pattern to handles with ornate handle ends - maker and pattern unidentified but makers marks are R.I.S. Sa. With an additional 'i/o' mark similar to how WMF used it.
here are 2 older Chinese spoons with characters to handles, the 'triple' one is by 'HPK' (no further markings), the one character example is by 'KMS' with a further Chinese makers mark. Both have gilt washed bowls.
