A Antique or Vintage ? perfume scent bottle green glass sterling silver bird head

A beautiful antique or vintage ? perfume bottle with a green glass body and a solid silver flip top modelled as a birds head with a tiny little inner stopper. This is in excellent condition, Its not marked but has been professionally assay tested with a gun as solid sterling silver. Its in such good condition I can't make up my mind if its antique or vintage, there was a fantastic firm in the early 80s making claret jugs etc which were fabulous quality and pretty expensive at the time so I wonder if this is one of the designs ?.
