old antique white porcelain shell oyster dish, divided plate w/ handle

Victorian era oyster server, heavy white porcelain edged with gold, 12 1/2" across the shell shaped bowl. This is German china, marked only SPM, 1860-70s vintage at our best guess from the marking.

It's in amazingly good condition, a little bit of wear to the gold but otherwise nice, no staining or discoloration, no chips or cracks.
