The spoon, if it is one of Weston's forgeries, and I think it very likely is, is a great find.
I'm always amazed at the risks forgers took at the time, the penalties being so severe. Even though the marks are likely counterfeit, the spoon itself is probably silver and the risk taken was just to save on hallmarking fees and the duty, for that, transportation for seven years was the likely outcome if found out.
I'm not aware, or maybe just forgotten, of the origins of the photo. It's possible that Weston may have used more than one maker's mark punch when knocking these out.
As always, it would be good to hear the thoughts of others.
