Received my copy this morning, beautiful, really pleased with it!
Re the coding at VSL, the pieces I have shown in other threads are all signed differently. They all have the Sam Herman signature, the very large vase is signed V200, dated 1989, the smaller one is signed and marked Val St Lambert, has a number VAL125 and the other large one just the number 252 next to the VSL mark, but both dated 1979.
I guess with so many pieces it's unavoidable to come across these differences.
