My brother recently found this helmet and paid a relatively minor sum. I am confident it is old, the emblem is similar to the 29th, but not exactly a match. The chinstraps seem a little off and the brass hardware T1 catch is not something I seem to have seen before? My first thought is that it might be Israeli because of the star next to the name, but I don't know. Is this US? Any thoughts? Thanks ABN

Hello, i have this demoliton platoon chest I have noticed that it has several markings and I don't know very well what they mean. If someone could help me, I would appreciate it. Here are some photos of the markings mentioned above.   In some images I can see inscriptions that say demolition in red, I also see a big red one, I would like to think it's from the Big Red One, I also see in another photo the symbol of the engineers, the red castle with a yellow stripe   This copper was found in northern France

Hello, sorry for the time and thank you for the info   

Wow that is an incredibly beautiful piece of history. I never knew of its existence. Too bad it rests I a safe and not out for public viewing. Thanks for sharing. 

I agree 100%. And I've had two really nice, originals and I think the last one sold for 525ish, on eBay. That was probably 3 years ago.  

What a beautiful medal. Thank you for sharing it. 

Some 1917 dated leggings i just got off ebay, ive never seen any with the extra hooks. Asking for measurements, they said they are 15.5 inches tall, other measurements correspond to a size 1 

I would say that AA stands for anti-aircraft artillery. I can't add much beyond that other than to observe that it would make sense for the state of NY to have anti-aircraft installations.

I recently acquired this M1917A1 helmet. It started life as a British MkI helmet that was supplied to the AEF. It was manufactured by Thomas Firth and Sons. The chinstrap is marked H.M. 103 CAC (AA) S. (I think, it's hard to read) I believe this is a Coast Artillery Corps unit, but I can't find a unit with this designation. Painted boldly on the front is a large N.Y. The helmet came from an Antique Seller on Long Island, NY. I know there were multiple CAC units stationed there before and during WWII. I was wondering if anyone has any information on this particular unit? If anyone could help me out, that would be greatly appreciated.
