NER Raven Z Class/LNER C7 + LNER C9

[WestRail 642fan]

Put simple, i want to see some more ready to run pre-grouping models. So my wishlist is for the Raven designed Z Class Atlantics for the North Eastern Railway, later reclassed as C7s under LNER

The LNERs C9 are Gresley rebuilds of the C7s, the rebuild including the installation of a booster truck below the cab, effectively making the C9s a 4-4-4-4. Only two were rebuilt, these are 727 and 2171.
