Hi fellows, does any of you have photos or drawings of Chinese Civil War warlord armies? I'm interested in the uniforms of different warlords? I already have 2 books on the subject:

Osprey Military's Men-At-Arms Series (306) Chinese Civil War Armies 1911-49 by Philip Jowett and Stephen Andrew
Oxford in Asia Paperbacks' China's Warlords by David Bonavia

The first book got quite a few photos and tons of illustrations and drawings on different warlord armies such as the Fengtien Army, the "Tin Hat" Brigade, Feng Yu-Hsiang's Army, Nationalist, Republican and Communist armies. The other book by David Bonavia had a few photos but goes into details of a selected warlords' way of life and the battles they fought. The accounts were from western advisors serving the warlords of the time and are quite intriguing.

I'm hoping though for some illustrations of other maybe less known warlords? Like the Yunnan or Sichuan warlord armies? Does anyone know what they looked like? Thanks !
