Well thats what I thought, but in an auction this week there was a painting of two stablemates fighting it out in the King George, but they were both bay and not a grey.
No date on it and no names (didn't manage to get it either but still interested). The bay on the nearside was wearing red and white colours and I think the other one was too but they weren't of course necessarily owned by the same person anyway. I can find a list of winners but not 1st and 2nds.
