This one was published recently in Serbia:
"Serbian Army - Weapon Of Our Victory 1914-1918"
By Branislav V. Stankovic
In my view an interesting book!
Besides the said Serbian armament the book also treats the ammunition for the weapons, packing, clips and headstamps. Also grenades and edged weapons.
The book has English captions on every chapter and is excellently illustrated.
470 images (400 in color)
