Help ID military piece

Hello, got this at auction yesterday in a lot. No clue what it is from. Any ideas what this is. It clearly attaches to something, but what I have no idea.

 

I don't know but the size will help

 

About the size of the palm of the hand.

 

It reminds me of the cups my brothers used with their hockey uniforms. Is it possibly something along that line? Or possibly knee protectors.

 

Only if you're going to screw it into your pelvis...........

 

Ha, ha, ha, you crack me up! It is a similar shape though, lol

 

Your jocularity this morning is stellar....

 

FULL IMAGE even better.

 

Seems familiar....

 

I also thought about it being a protector of region, but yea the holes on the side i dunno. Not unless a rope or tie went through the holes to secure in place. Will be interesting if it is that.

 

Blackout cover for a jeep??????????? WTHDIK!!!!

 

Belly chuckles here! Funny funny funny!

 

Now THAT is definitely a size matters issue...

 

Well this might be a timely find. A cast iron athletic protector could be useful these days and it is made in the USA. Mr. Trump will love it.

 

What about a bridel rossette?

 

Can that work at only two attachment points.

I tried that once.....
Don't recall a honeymoon or anything else or about 3 week's of missing time.....

 

Whoops, wrong bridle. I noticed a small hook/catch inside and possible something missing opposite that. It does look similar to some of the vintage rossettes I found online. KingofThings, you have me laughing again. Thanks for that!

 

I try...

 

It says US but that doesn't make it military. Looks like a part off some kind of vehicle.
