It is a T60A without a cotter pin hole in the top jaw so you are good to go for a G503.

If you can switch the nut for a large pattern thin nut that is a nice touch. Originals were 25/32" wrench size, I don't think you can find them anywhere as current production hardware. But you should find 3/4" which should look the part.

Is it possible to fix a year of production for my pintle hook or at least an educated guess? I think that these "diamonds" and the number 4 on the upper part could be a hint.

And could the mark on the left side just before the eye bolt be a Wilson foundry mark?

Thanks for the hint. I am sure going to look for a bigger nut.

But in the end: Who knows what happened out in the field. Perhaps some workshop had no suitable nuts and bolts available and so just used what lay around. I therefore especially deem g503s that were over here in Europe historically correct, if the parts added were available at the time the vehicle respresents and in the TO. Soldiers on the front surely didn't mind about the looks of their vehicle it only had to be fixed as soon as possible and run well.

So a late war pintle hook on an early g503 is ok, as the right one could have been damaged and replaced. Even a slat grille pintle hook on a late war G503 is imaginable to the same ground as the pintle hook could come from a scrapped vehicle.

I therefore try to have every part in factory standard, what can be a very hard and expensive thing to do over here in Europe, but I am not afraid to find other suitable solutions.

Nevertheless I appreciate any hint for what could be wrong and should therefore be changed so that I can check what's possible. I still have a long way to go in restoring my G503.

I was led to understand that there were four different types of pintle hooks used on WW2 jeeps, with the late one having a coter pin in it, am i correct on this ?

There were no cotter Pin in the GI issue G-503 Pintle Hooks, it is a post 40's detail on the Civilian Hooks. Check the 1951 SNL's The Army issueed Stamped Pintle Hooks as replacements and also stocked the heavier Korean War era ORD 7073209 M-38/M-38A1 Pintle Hook WO-800929 for replacement installation on the G-503.
Manuals, Manuals, Manuals, and old time parts counter experience is a good start on learning MV's. The Pintle Hook story involves a mix of GI and Civilian manuals.
The Holland Hitch manufactured Pintle Hook as installed on WWII Jeep has morphed into at least a half dozen variations with details such as jam nuts, cotter pins, mounting hole size, forged ID markings, visable manufacturing methods, finishes, different rivets, etc. They will all fit and will pass the 50' test.

So, I finally got it.

I am quite glad to have found it, looks nice.

But does anybody know the meaning of the markings? T60A and T62X is clear, but what about "4", these "diamonds" and the wheel/flower-thing?

Is it certain that the late pintle hook did not have the safety pin ?
I do not think mine has ever been off my -44 MB and it has the 25/32 nut

your Pintle Hook appears to be genuine, it does appear that the safety pin and chain have been added on by a previous owner. The chain and Ctter Pin are not the style installed by Holland Hitch to the same model Post War Pintle Hooks .

The previous owner is the Norwegian army, could it be that they made the hole for the safety pin ?

An old-timer I was in the service with told me once that the old hooks had a "squared" nose at the top, and usually no cotter or chain, although some were drilled
