Tuscan coin silver gravy ladle, King & Brother, unknown

This gravy ladle is 7" and in excellent condition. There are no dents or repairs. The pattern is Tuscan. It is marked "King & Brother". Although there are several Kings, I can't find a brother. It also has an interesting raised eagle that must have been part of the Tuscan die and is probably a manufacturers mark or possibly a journeyman's mark which I am also unable to identify. Ca 1850/55.
