So couple of days ago, i saw this beauty for sale (unfortunately without the helmet) and i was very interested in buying it, but now im not so sure. It looks fine but after looking at some of the other Adrian helmets with the same kind of plaque, im wondering of this is a fake one, especially because i noticed some people mentioned that some of the plaques were made in 1930, despite the "1914-1918". So i was wondering, is there a way to identify these plagues or is it just hoping for the best?
I hope you can help
