It's not on their website yet, but for those looking for a copy of this book by Brian Wilson, it would appear Camden are having a new print run made, due out in late March, projected price GBP29.95.
Recommended for anyone with an interest in building a small steam loco themselves, it also has several chapters on building your own rolling stock.
The book has been out of print for some time, so this should reduce the price of s/h copies on Ebay........
