Assorted 7 1/4 inch gauge castings

I'm sure some eagle-eyed ready will tell us exactly what these are, for now they're assorted castings - mainly 7 1/4 inch gauge although I could be persuaded the cylinder blocks are for a large 5 inch gauge engine. All in cast iron, six spoked wheels, four disc wheels, two cylinder sets with blocks/covers/valve chests/pistons, horns and axleboxes, eccentric straps along with a couple of other odds and ends.
