That is really neat and something you don't see very often.  Nice find!   OD

Looks like a good 1/5 helmet to me, but I consider @warguy the final word on these.     He’ll be along shortly…    

Oké, I just put it out there, knowing there are no stupid questions...🤪   Can pink trousers be combined with gaiters? 

I looked closer at the photo in the Jones book example  and it has the small holes. The price seems a little high. 

I would be willing to bet your insignia was in a fire giving it the black appearance. However black insignia do exist, the gray uniforms that were worn during WWII called for black insignia. Most men opted for the gold and silver mainly because it looked better and they did not have to buy another set of insignia just the gray cover for their combination cap even though it was not to regulation. 

Hi to all american friends,   This helmet is going to be sold in an auction.   I'm not very familiar with US Marines' helmets and I'd appreciate to have your expert's opinions about this one.   I put some pics below.    For this moment, these are the only ones I have.   Thank's a lot   Dominique

Hereford Texas prisoner exchange was the second largest pow camp in the United States. Housing over 5000 Italian prisoners. The prisoners helped the locals farm and update there churches. What an awesome piece of history in this crate.

Glad to help. AZNATION is always great at researching our great veterans. I’m always amazed at what this forum member uncovers for people seeking info. Well done! Jeffro
