Please to purchase copies of my new WW1 Middle Eastern Painting guide, published by Partizan Press, available on the Caliver Books website.

In this first of a series of painting guides for wargamers published by Partizan Press, Mark
Hargreaves takes us through a series of step by step photographic tutorials that cover the painting of flesh tones, khaki drill uniform, khaki serge uniform, horses, camels, guns and vehicles for the British, Dominion and Indian Army troops that served in the Middle Eastern theatres of World War I.
The painting guide will also suit the same troops up until the late 1920s and so will be of interest to those who game the Back of beyond and Interwar periods.

The guide also contains advice on simple conversions involving swapping heads and
the basic use of greenstuff to add details to your miniatures.
