#5150 Morgan Stallion
It's a pity about the gouges in the plastic and the airbrush burp on his pastern, because this guy is otherwise stunning. My other models from this run are more orange and their points are closer in colour to their body, but as you can see, this one has a light apricot body with darker joints, and an almost cranberry coloured mane and tail which are also beautifully shaded.
Though it can be difficult to differentiate between the 1976 #5037 and 1989-94 #5150 issues, this model is unlikely to be a #5037 as he is missing his mold stamp, which, going by our post about mold stamps, means he's more likely to be a #5150 released either in 1989, or 1991. He won't be from any later than 1991 because he's an old plastic model.
