An Eagle Horseshoe bearing the Coat - of - arms of the German Duchy of Wuurtemmburg and the motto: "Fruchtlos und Trew". Translation: Fearless and loyal. Note the tip of the eagle's beak appears to be missing. More often than not this was due to the molten metal not quite reaching that area, rather than being broken off.
I suspect that this trivet may have been associated with some German-American Fraternal group. This example does not appear in any reference book. However, Kelly & Ellwood (A Collector's Guide To Trivets & Stands) picture a variation illustrating the Wuurtemmburg crest on Pg. 245, top center. Kotrba collection
