Sorry to drift the topic a little.
The second photo of No7 (unlined), the cattle truck lurking behind the smokebox, the large, freshly painted "M" seems to be in the wrong place for C&MDR?
Or was it just lettered C (door) M or C& (door) MD?
Can't think of another company that would have the "M" there?
Edit:- It looks very similar to the C&MDR Cattle and Goods Van I posted in the "Resources" section which you guys still can't see 'cos it's not been approved by the mods yet.
