With no catalog number (1301) on the pot and no stylized logo (came out in late teens?) I think the pot is pre c.1924. Or, perhaps, Wagner never changed or updated the pattern to include the catalog number which appears by the 1924 catalog. Also, Troy, did Wagner change to a more usual bail handle ears on their later dowlegs? I don't know for sure but it seems to me that I've see some Wagner dowlegs with the usual style ears or pot handles.
