I have a soup or punch bowl but not sure what they are made of they both have marks but not sure what they mean can anyone help?
The bowl has the name Frank Cobb Ltd sheffield England followed by the numbers 129 2886-83 followed by an arrow.
The spoon has the sane arrow then the following 1958 W.B&S Ltd KF.18087

Any help would be appreciated.
