I am new to GMB ... I am having a difficult time finding archival material of any kind for the 'wave' crystal pattern, and would love to have the advice of all of you so knowledgable on Stuart crystal. I have been pointed to the Broadfield museum (of course closed) and the Queen Mary's archives (very hard to access), and the Shipbuilder (only a short paragraph) As I am in the U.S. I am finding a hard time of it. There must have been tens of thousands of pieces made but I cannot find a single sheet identifying the shapes. And of course this pattern was unmarked. Any direction at all would be so greatly appreciated, as I am working to create a reference guide for this highly sought after pattern.
