Might be stating the ******** obvious, but these vehicles ran in quite large trains, not as singletons. As there is quite a lot of detail in them they aren't going to cost less than £30 each. The eleven wagon train above will therefore cost £330! If you want empties and loaded, £660!
Now I'm a CLC freak, started my spotting at Northenden c1950, but these are not for the faint hearted branch line enthusiast, not at all.
