Adverstising him currently as GOV approved is misleading those whom have already bred to him and they could have trouble registering their foals as such. As a breeder the first thing I check is for current registration with the applicable breed organization a stallion is "said" to be approved. As friendly advice, because he is interesting, make sure you can back your ads up! I hate to see those starting out in breeding get off on a bad foot, especially when starting with nice stock!
Best of luck, and I will keep up with his progress.
