European Horses

[Lindros]

I am currently looking after a european horse named 'Master Nergal'. I would love to find out more about him. He's supposed to be a Grade 1 winner!
He was imported this summer with the intention of running him up here in Canada. He flew to the USA and was vanned up here. During the trip he got VERY ill and that's why he ended up at the farm I work at. Luckily he's much, much better now!

Any other european horses I have met usually have a lip tattoo which starts with a *. He isn't tattooed. How do they ID the horses in Europe?
