First class Dining Car interior - LNWR - Wonder Book of Railways c1916

Although illustrating the same article in a Wonder Book of Railways, I am fairly sure that this is not the interior of LNWR Dining Car 561 shown in another scan from this book. www.flickr.com/photos/phil-seaford/8496590040/in/photostream
Although not dated, a chapter on Railways in Time of War, talks about the mobilisation of the british railways but does not give any indication that WW1 had ended.
