can definitely be proud of your nice collection, you have many post war examples that I miss and that I really do not know very thoroughly, I'm learning many things from your posts and those of Bruno.
Although I'm not an expert on the subject, I know much better French helmets of the two World Wars.
I do not know if you had already seen these my post, but I'd like to have your opinions on these helmets, I think it may be interesting for you, there is also an example for veterans with "Great War Plaque" similar to yours.
French Adrian helmets 1915
French M26 helmet
Many thanks for the kind words Roberto and glad you enjoyed viewing my collection
Very nice collection with a good evolution of the french helmet.
Nice to have the Naval infanterie. Not an easy one. I just got mine 2 weeks ago.
Also nice to get the googles. Maybe the most difficult part to get and giving a very nice display
Thank you Bruno for the kind words the Naval infanterie m15 is one of my favorites ,as for the goggles I've not seen a surplus pair come available for a long while here in the UK
