Vintage charm or necklace pendant shaped like a Dutch windmill with rotating blades. Made of silver colored metal with cobalt blue painted enameling. Unmarked. We're unsure of the age on this one but feel it falls in the 1940s to 1960s range. Measures 5/8" long . Overall condition is very good for this type of vintage charm with some minor wear to the enameling. It is also missing the ring that would hold it onto a necklace or charm bracelet. We can add one for your for an additional charge, or it can easily be replaced by the new owner.
