During the 1940s, Griswold faced increasing financial difficulties due to competition from other companies such as Wagner, and by 1946 no members of the Griswold family were left in the firm. Ultimately Griswold sold its molds, tooling, patterns, patents, proprietary rights, and trademark rights to Wagner in 1957. Rather than retool a pattern - they just engraved the one they acquired. Cast iron double stamped with the words Wagner and Griswold (and therefore made after the 1957 sale) have almost no collectible value - but they are cool no matter what they are valued
