My heart starts racing when I spot a really special brush or broom like this one. I believe whisk brooms/brushes of this sort of construction are generally referred to "turkey wing"--though the bristles on most are more angled. Here, brass wire beautifully wraps both the horizontally running bristles that form the handle and attached bunches of bristles that hang down perpendicularly, secured again with string part way down. The lines, patterns, and textures on this make it feel as much like sculpture as a functional object, and to my eye a truly stunning one. I'd guess it is more than 100 years old.
The brass cap at the end of the handle is a bit loose, and on one side some of the string stitches have come loose and some of the bristles seem to have been trimmed at some point (see photos). Overall, it's in good condition and certainly could be used, but I'd be much more inclined to hang it or display it so that it will remain beautiful for many years to come. 10 1/2" from tip of handle to far tip of bristles (measured at an angle); 4" tall (measured straight up and down); 5/8" deep.
