Greetings! I just picked this one up, a M1915 Adrian helmet painted black. Like Italian models, it is not pierced for a badge in the front. The interior, however, has what appears to be an ersatz felt/wool liner that is quite old and worn. The chinstrap reminds me of the postwar Balkan ones affixed to M33 helmets that are common today.
The exterior is black and in decent condition. There is general wear to show that it's been on there a while. There are no markings inside or out that I can find. I would appreciate any help identifying where this came from or where it might have been used! Thank you for any direction or insight you might be able to provide--please excuse the poor photos, as my camera was having trouble focusing indoors today.
