I dont know that any of it ultimately really matters. I just always thought that the info the old time box call makers put on their calls was kinda cool and made the calls more interesting, with the provenance of the woods, its history and all.
Of course records can be kept of pot woods types and which strikers came with the calls, dates, and so on, but records get lost and calls get passed on to future generations and will "outlive" callmakers and original owners.
