Hi,
  I'm an old cook, have cooked with cast iron for years, but have just recently gotten into trying to collect the Griswald and Wagner cast iron.
  At a pawn shop the other day I bought a 5qt kettle, on the bottom it says 
           Wagner's 
             1891
            Original
  Cast Iron Cookware
seasoning instuctions

4
ready for use - reseason as necessary
        5 QT DUTCH OVEN
          MADE IN USA
I didn't find it in the book on Griswald and Wagner I have so was wondering.
                   Thanks, Jan     :)
