David,
Depends on what you "see" in the book?
I see a 1937 collectable maybe, an illustrative "golden times" book showing Trains in Scenery or maybe a touristy look "back then". A look at past times can't replicate many scenes today like that due to moderisation and urban sprawl.
I'd be glancing at it and put it back on the shelf, mainly because it isn't nuts and bolts gritty details.......
but if it was on the C&S......
