I have an antique piece that might be what you are looking for. Im not displaying it right now and have no room for it in the near future. ( Log home, very limited shelf space )

PM me at pedfjords@aol.com and I will take a picture of it for you.

Its dark grey, its metal and its a tacked up, ornate, rearing horse. My mom got it from a family of a lady she used to help take care of after she passed away and my mom gave it to me. This lady only had quality stuff from years of collecting, but I have no clue about its history.
