help ID silverplate EPNS flatware with A FIGURAL MARK

New here, and would very much appreciate help identifying this flatware.
I am enclosing pictures.
the hallmark or symbol looks like an animal to me and since the pieces are only signed with EPNS i have no idea of maker, age or value.
MANY THANKS TO ALL!!
