To pintle or not to pintle?

The lunette rotates up and down in the ring. The pintle needs to rotate . On military trailers , the lunette ring rotates. I posted a link to the rotating pintle.

On the WWII trailers, the lunette ring sits in a lateral tube. It rotates/spins 360 degrees on its axis facing forward. Look at the first picture in post 61. The lunette ring also pivots/swings up and down in the pintle hitch. But even if neither can rotate, there is enough slop inside the ring to allow for some twisting movement.

Mine will rotate laterally as mentioned.
All pieces came in the mail couple of days ago but it’s 38 outside and I’m not interested in camping out in the barn to work on it in that weather. Hopefully the sun heats things up this afternoon and I can give it a try installing it.

Ok... here you go with a "regular" pintle hitch.
Lunette ring in the down position. Looks like 90-degrees to me (it is just hanging there). You can see all the room (or "slop") the ring has inside the pintle jaws for twisting movement. The weight of the angle finder is actually having the lunette ring thingy back beyond 90-degrees when you look at it. It could go back another 45-degrees if it wanted to.
Lunette ring in the up position. Again, looks like 90-degrees (actually is a few more in this picture as it has gone beyond 90-degrees and is leaning back further some). My spare tire would keep it from going the full 90-degrees up in real life.
And here it is with the lunette ring in the "twisted" position. I could only get one good picture since I was taking these by myself. But twisted right and left got the same angle measurement @ 27-degrees.
In summary
90-degrees (+) Up.
90-degrees (+) Down
27-degrees "Twisting"
So my Nato Hitch I've got coming in (last I heard should be here Monday, 7 Feb) will allow the lunette ring to literally twist 360-degrees. As far as I know, I've never overtwisted (extended the limits) my current set-up. But it will be nice to know with a rotating pintle hitch I'll never have to worry about it.

So I'm thinking you really dont need much more "twisting" for the trailer than the 25-27degs you guys have measured.
lets say you get your vehicle at about 20degs off camber, then that could allow the trailer to get up to 45degs off camber, thats a lot of off camber.
Maybe I am wrong, but that seems like a lot to me.

FYI- some of the old WWII trailers had reverse threaded lug nuts on the driver's side. The studs have an "L" stamped on the end which you may be able to see. Just a thought.
So that Curtis dual pintle really has some extra meat in her to limit the travel!
Good to know!

Do me/us a favor. Measure the outside and inside diameter (hole diameter) of your military lunette ring. I want to compare it to our 2" receiver ones we use. Thanks.Got the new lunette installed but have been fighting with seized lug nuts on the driver side.
Been a pain in the butt for a week now.
