Thanks everyone for the great comments and ideas. He does have the build like the hancock's that were mentioned for sure. I have continued to do more research and the one point that has me thinking at least part American Cream is the fact he has amber eyes. He also has that laid back personality of the draft horses. Sat for 2 months and went out like he hadn't missed a day. He also has a hell of a stubborn streak when he wants too!!! And not lacking in power when he gets that way LOLOL
In all honesty it really doesn't matter to me, he's a gelding so not like I'm looking to breed him. But he is my heart!!!! Just love this big boy to death!!!!
