I'm sorry I didn't respond sooner, I've been busy these days.
I have included new photos.
The screws looks like 7mm approx. The chin strap is like 1cm.

Thank you very much for all the information you give me.
First of all I would like to apologize for my level of English, I will try to express myself as best as possible.
I update you with more information about the helmet:
In the first photo, you can see that there is no type of inscription...
I've had this French WWI helmet for a while. Is it possible to know if it is original or if it is a recreation or fake?
Your opinion would be very helpful to me.
