Modified Flak Helmets especially from Italy or the MTO

[gitana]

Does anyone have, or have photos of, an M1 helmet, modified for use as a flak helmet? No need to post the ones that you can find with a quick search, but I was hoping others are out there. I'd especially like to see any that were found in Italy or the MTO, or that can be attributed to the 12th or 15th AAF. I'm not sure if it was done in that Pacific but that would be great to see an example from that theater as well, if any exist.
