Yes, I had Sulphuras Apache Promise, who died during a red bag delivery while on lease to a breeder-- who definitely was incompetent. And Promise had produced several outstanding babies for me years ago.
I unfortunately don't have that information, and I even checked the "Way Back" machine to see if her original website had been archived, but couldn't find it.
Hopefully, she'll be able to help you and even recognize the other horses.
Sorry I haven't been able to be much help, but it was long ago.
As to a show record, there are no "National" shows showing on the website, but sometimes if you call the AMHA/AMHR offices they can tell you if he was shown, and what he might have achieved.
