Antique Rogers Portland Pastry Server or Jelly Knife

A beautiful and unusual piece of antique silver plate. This server could be an aspic server or jelly knife, but probably is a pastry server. What ever it's use, it's gorgeous!

Marked "1847 Rogers Bros, A1" and the pattern is "Portland" which was designed by Henry W. Hirschfeld. This design dates from 1891.

Measures about 7 1/2 inches long. Great condition.
