Ho avuto una prima risposta (non definitiva) sull'elmetto grigio:
"It looks like a British military fire service helmet to me Paolo, judging by the strap colour and paint. Is there evidence of a neck skirt?"
Io ho risposto:
" Did the Fire Service have the grey colour ?No traces of a neck skirt"
in risposta:
"I believe so. I have one somewhere here with a neck skirt. It attached under the liner but was easy to remove. I believe that is what your helmet is. Is there a date on the liner?"

Mi si chiede se l'imbottitura reca qualche data.
