Absent Kathy, I am not sure that anyone is keeping a running list of these anymore. The data base, had you seen it, was not exactly a database. It was more of a compellation of Dennis and Kathy's notes. While Kathy was actively working on her book and still active here, many of us were in the habit of letting her know of Morris canoes we had located and any interesting, related details. After she went "off grid", I don't think that has been continued.
I am continuing to note any serial numbers that turn up with provenance that affect the Morris dating table. I am overdue to make one change to it related to a refined date that became available since I last revised it.
