Thanks Spyder! I'll have to do some more digging. If this is the correct Zeus (which I'm pretty sure it is), it makes it a little more interesting and I'd love to find out when & how he was approved, and try to track down any other half or full siblings that are registered Hano. The similarities in appearance between Zee and some of the other Zeus offspring is truly remarkable, even the facial expressions!
Based in the face markings and color I am 99% sure it is the same one.
In the video you posted, the first thing I thought was the poor trot and that was even mentioned in the site I posted. The date of death I missprinted in my original post and noticed it said 1988 but that could be a misprint.
There are some nice lines in this one but the Furioso line can be difficult to work with.
I believe the Matador line IS Hanovarian though.
One more thing.
If your horse's dam was approved and registered in the Hanovarian studbook and the sire was not the mare owner can present the foal to either the sire's studbook or the dam's--where ever they feel it will be accepted and the Hanovarian is the most prestigious.
