Thanks all!
Norbit as he was known here was always a very nice-looking colt and a real steal - Paul T bought him in utero for 1500 gns! I paid nothing for him as I kept the mare and foaled her as per our usual arrangment and we sold him for £8K. He was a February born, too, which obviously helps. We have his ISHIGURU half sister in the field and she's an extremely good-looking filly too.
Of course, that comes from the dam, as Troods will of course tell you, as she now has PETROVNA as a much loved pet - albeit a useless one!!
