That is correct they were in the same class. I was at George Wilson's loft in the early 80's just after he moved to the compound on the railway embankment near Murrayfield stadium. There were another 3 lofts on the site. They were experiencing difficulties getting the birds to exercise as they would land on a high factory roof about 200 yards away. Big George soon sorted that, he got himself a catapult and fired stones at the roof until the birds broke this bad habit, it didn't do a lot of good for the asbestos cement roof mind you!! George was always looking to improve his team, before he finished with the birds, he brought in some birds from Fountainhead stud of the Verschelde bloodlines, these were very successful too. Although, I think George would have won with most families of pigeons as he was a class fancier.
