Hard Plastic Horse Lot of 2 Gray & Brown and similar items

This pair of detailed little horse figures are molded in hard plastic. The gray horse is unmarked while the brown horse is marked "Made in U.S.A." They each measure approximately 2 1/2 inches tall and 3 1/4 inches long. We're not sure on an exact date, but they're easily from the mid-century era. The gray horse is likely the older of the two, with crisper mold lines. They are the same mold and have saddles and reins, with mane and tail are blowing out behind. There is a spot of damaged plastic on the gray horse's rear flank, otherwise good vintage condition.
