I look forward to your article. They are much rarer in the US than the 1930s Chinese weights, perhaps by a ratio of less than 1 in 1,000. I suspect these are made by the same factory that produced the flat profile nosegay on double latticinio. I've done a rod count of the nosegay and they matched the count for NEGC, while the Chinese nosegay did not. While similarities help our discussion, they aren't proof.
