Dear Andrew,
For Martin Evans books try
(a) Local book fairs, even if not transport-related
(
book stalls at model railway/model engineering exhibitions
© Internet - these are a couple I think worth trying:
www.gg-books.freuk.com (Geoff Gamble Books)
www.pearman-books.com (Bob Pearman Books)
There is someone at Matlock in Derbyshire, (Bill ???) but I don't have the details to hand.
Look in the adverts of 'Model Engineer' and similar mags, including the model railway magazines for other potential book sellers.
Hope you find what you want,
Regards,
John Webb
