If you can lay your hands on a copy of the August 1957 issue of Trains Illustrated, you may be interested in the article by R.S.McNaught, The Robinson "ROD" 2-8-0s, pp432-8. which deals with the post-WW1 disposal of the government RODs, not only to a variety of British railways, but also to more exotic destinations, such as Shanghai Hanking Ningpo Railway.
