It's been OOP for years, sadly, it's a great book especially alongside the Central African volume and Peter Abbots OOP Foundry book on Colonial Armies in Africa. It took me years to track down affordable copies (and even they where well over the original price) of the East Africa and Peter Abbots book on eBay. None of the OOP Foundry books every seem to get re-printed so I wouldn't hold out to much hope sadly.
