I'd never seen a rug beater like this before when I found it, and just fell in love with the look of it, with its elegant form and especially that beautiful tightly looping wire, which casts a pretty wonderful shadow. I've since learned this is called a Herkules rug beater, and that these are made, usually in German, for pretty heavy duty rug beating! The shape of this one is the loveliest I've seen, with an especially long wire neck giving it lots of flex, and a nice, well worn wooden handle at the end. 

23 1/2" long x 5 3/4" widest x 7/8" deep. Excellent condition. I am not sure the age but its definitely got some years on it, though lots of good use left in it.
