It is slightly odd as the LNW prototypes look great but you have to remember there have been two RTR Midland Compound models out and a 1P in the works for much longer than there have been a Coal Tank (something which many, including myself until recently, think of as solely a goods loco) and much more recently, a Precedent.
Additionally I would argue that the clerestories look and feel 'more LMS'. After all, they have always been red!
