Left front looks like a club foot.. but it also looks like it could be salvaged with regular farrier work. He may need to be shod on the front to help the foot stay correct.
He has nice bone although he is a little leggy. I think his looking extra long legged will probably improve with more feed and work to fill out his body. His top line looks good though his back is a bit long and weakish in the coupling area. He has nice withers. Again.. the weakish looking coupling would probably improve with groceries and as you build up his hind quarters. He may be a little sickle hocked, but it is hard to tell from these photos.
I would spend the money to have a farrier look at him and give an opinion on his feet, especially the left front foot so you know what you are getting into, You will probably have to pay the farrier the same amount as if he was going to trim the horse.. but it is money well spent to know exactly what needs to be done and how long it will take and what the continued costs will be to keep that left front from clubbing over the the tendons contracting.
