Very late to this party but I just had to say I'm speechless...what a collection!!! MY BRAIN ACTUALLY HURTS! 

Bayonet16 I have a couple of questions for you about YOUR Colt/90.  I sent you a message about it.  The short answer about the Eickhorn connection is that the Colt roll mark is nearly identical on both the Colt/90 and Made in W. Germany M7s.  Also the latch levers on the latch plate are identical.  In addition, on one iteration of the Eickhorn Colt marked M7, the U.S. M7 mark is identical to the Colt/90 M7. Marv

The closer I look at it I have to agree with you. I can see the US is a different font as well...no serifs on letters. Also not as "thick". The ADK on scabbard is different than those on the guard. Not being a sword collector and wanting a Civil War "representational" piece many years ago this was a good find. I never compared the markings to my 1860 cavalry which I picked up a few years later either. Well, that's what is great about this forum, you learn new things every day. Of course now I want to get rid of the sword and will have to state it's markings are "questionable". Thanks again for your help with this.    S

I have never seen the 67 green version before ever for sale/never seen it in person or picture until now. I'd imagine it's rare or at the very least hard to find. 

Thats a brass deflector alright.  Good pix.

Hink441,    There was no squadron designations under the cover. It was a local find in Eastern North Carolina, probably from New River MCAS but who knows. It’s definitely a USMC Helicopter helmet

Excellent!

I think that you are right it's a tin type--- I also have a World War One tin  type  too. When I first got my I thought that it was really late for a tin type--- Nice find

Wow love it! Great collection
