I also found this bay Running Mare at Countryside Antiques. I had not realized that I did not have the bay in my collection. (Gasp! A hole!!)
Sugar, #124, 1961-/1963 - 1973, $15, Countryside Antiques, Lebanon, IN, 7/15/17.
She's semi-gloss, too!
And, her mane's oddly outlined at the factory (look at the curl.)
