James, as usual you've done justice to 2 fine Brush/Mirlees machines. I've always liked the presence of the 60's, and the names of course, Schehallion and Helvellyn being favourites, probably from my mountaineering days.
Isn't it a crying shame that there is a long line of them languishing at Toton, and they'll probably never turn a wheel again? I suspect they'll eventually be scrapped on site being too far gone to move again.
