I did get the date wrong in my first post when I said 1960's and I probably made a mistake when I said a Guild initiated legal action. It was more probably the Assay Office or the Crown that initiated legal action.
I got these in the 1980's from my father. He said there had been a bit of controversy at the time as these links used the Hall Marks as their main theme or selling point when in fact they were supposed to used only to certify purity of metal, maker, etc.
So, yes, cast Hall Marks do exist. The only reason I point this out is that when I see "never" used in this hobby I wonder how long the statement will stand.
