Képi Mle 1914 1st Type of the 12th Regiment of Line Infantry in Tarbes

Manufactured in France, horizon blue cloth, black leather and blue-painted brass ventilation tacks.
The Mle 1914 was an updated version of the Mle1884/14, itself a blue horizon version of the old red képi of yore, and sported a low profile more adapted to the fighting conditions of World War 1.
