A rough idea of how it looked in 1879

Absolutely Genuine.. From what I can tell by your photos, starting with the steel......... You have a early WW2 produced McCord made front seam steel pot with a stainless rim and it has been repurposed up through the Vietnam War era with the black hard ware chin strap attachments. The cover.. 1959-early 1970's Mitchell Pattern.... Look at the ink stamping on the beach side.. you can find a date on that. The Liner.. Its a WW2 liner with OD3 webbing and a later era green sweat band installed. The maker of the liner will be stamped inside the crown. If you can, get a picture of the stamp inside the crown... and the  ink stamp on the inside of the cover.... Cool Helmet! It could have been used in the Vietnam War.. and the Korean war.. and WW2 for that matter? No way to tell for certain how or where it was used when? But the parts span WW2 through the Vietnam war era. Not a fake or a euro clone. Its all US.   Cheers!  

Well so much for my research….I’m leaning to and agreeing with the info “aznation” uncovered/researched.  Great job “AZNATION”!

The footprint in 1869. In 10 years the fort grew quite a bit.

Picked up a few items at an online auction. Never seen the Democracy brand anchors. Imagine they’re sweetheart type pins.

Clearly Paki IMO. D

Found in an estate sale of a usaf captain. Not sure if period from the UK in the early 60's or repo from Pakistan. Any help is appreciated.  

I’m not sure about any of this stuff really I got this helmet passed down to me and was hoping someone can help me figure out if its authentic and it’s worth. 

Same same .. awesome !!!

Very cool, I like it
