antique silver plate salt and pepper shakers w/ acanthus leaf, early 20th century vintage

Pair of silverplated cast metal salt and pepper shakers in acanthus leaf pattern. These are about 4 1/4" tall overall.

We believe they're probably silver plate over spelter or white metal, the plating is very tarnished and worn.

The mark is a crest or something similar, no makers name, but numbered 52.
