I do not know the maker of this sweet little piece, but it sure bears the hallmarks of the Griswold sad irons. It has the removable wood handle and is obviously made with quality.
The iron and handle is offered in “as found” condition. Please see photos. It measures 3-1/8″ long by 1-7/8″ wide at its widest. It is 1-3/4″ tall with handle attached. There are no maker’s marks that I an find on this piece.
