from the nose to the but it is about 9.5 inches long. from the top of the head to the foot it is about 9 inches tall. There is no markings that i can find.
went looking for a horse like yours.... came up with some nice vintage toys but the only one that was real similar to yours is this one. and it is a 'team' but the horse have the same body construction as yours(ie head stance, body shape, legs/feet) maybe they were made by the same company?
