Here are some photos of a French made NCO cap, i have in my collection. The cap is made by the firm Marc maitre chapelier ,Rue Victor-Hugo 24, Châteauroux. The buttons used to secure the storm strap looks to be French made buttons.
The cap has a removable top , the lining that separates the top from the cap is made out of gauze mesh , just like what you often see on German made caps.
