These are original, quite common here in the states, wish I had a dollar for every pair of these I have found!

The label says "Light, Armored Vest"

Take a picture of it with google lens

Stevens is very easy to find also he is the first result that comes up with a simple google search. 

Just type the words "General McKinney" into your search engine, he is easily findable. I found several articles on him and no its not the WWII General. 

Hi all,   This set just arrived. A Garrison cap and short sleeve shirt from a Brigadier General. I have no idea if the set is original, since there is no name on the inside of the cap and shirt but the price was very low. Is it possible to ID general McKinney by the ribbons?   The set also included the green trousers and I was surprised to find a name on the tag! It is named to Major General Pat M. Stevens of whom I can find a lot of information. I have no way of checking if the trousers were really his though..   Enjoy!

Thx opseccc. From the Gerber link the serial number 097XXX was produced between 1977-1981. Paid $325 for both knives. 

Just a reminder that live ammunition sales are not allowed on the forum:   RULE 10.2(g) - Selling Modern Firearms and Ammunition We do not allow selling of post-1897 firearms or live ammunition on the US Militaria Forum.  Pre-1897 weapons are allowed to be sold, as well as accessories for modern firearms, but no auto conversion kits.

I'm not sure but I believe so.

There you go. It’s the same as those worn on the ships, but, you’re right, souvenir.
