I would not say draft . Quarter or morgan or something similar type. Not heavy enough to be a draft cross. Hard to say in those pics. He looks okay, but he needs a good farrier and maybe a tad cow hocked ? And in one pic his knees looked wonky, but it could be the pic .. hard to tell.
Looks like he will make a cute little riding horse and project . Good for you for taking on these horses, even if you do sell them .
