I feel compelled to plug his booklet which is only available at the Bluebell Bookshop at present for £4.99 (see my book review blog).
As you can see the third edition (right) is very much like the second on the outside and both contain 32 pages with the same information, but he has managed to obtain a number of new pictures (some of which I have never seen).
Above: A little about Horsmonden and Goudhurst Stations
The clarity of the photographs are also better when compared to the earlier edition.
