I have a set of Walker and Hall forks. They do not have the Lion Passant to denote Silver Content and no Crown for Sheffield. Instead they have the letter H and a picture of a building with 3 crosses on the buildings 3 gables followed by the name HALL then the trademark flag with W&H inside.
Below is a picture of the back of the fork in photo bucket. You may need to copy and paste the link into your address above.

Any information about the forks would be greatly appreciated.
