Vintage Breyer Horse Proud Arabian Mare Dapple Grey Semigloss, made in USA.  I believe it's #215 but not 100% sure.  It measures approx. 10" in length (including the head and tail) and overall height is 9".  It's in great condition, no chips or cracks.  There are a few tiny black specks that may be noticed when examining closely (see last 2 photos).
