What is the Part Number, some,are, some aren't.

Well here is a box that I have full as you can see in the image here of new caps, and I know that they are not going to bring much since you can get one from any parts store, but I was just curious and here is the number I found on the yellow tag so I do not even know if this tag number is right either. But thanks for your input in this as well...

Hi RedArrow2016,

According to SNL G-508 (CCKW), radiator cap PN is: 850053. SNL G-501 (DUKW) lists two caps: 2178395 (early), and 2199928 (later). The 2199928 includes a chain.

Hope this helps.

Best Regards...

So this number that I have here then is not the right number then? I know the box says DUKW on it but I am wondering if these are DUKW caps now. And that does help out a lot just questioning the yellow tag on the cap...

There is one cap in the pic (with the handle) that appears to be G-506 and G-508, the others without the brass valves may be suitable for MB/GPW Gas Tank Well Drain covers, the correct Gas Tank Well Caps have two nubs on them, these are round but may fit the drains. Who wrote G-501 on the box? This appears to be a bunch of assorted caps dumped into a box.

Would you save me a NOS CCKW Cap with a Handle if there is a NOS one?

Sure I can hang on to one for you, and the box had that label on it when I was unloading parts out of a crate so learning so much about this stuff. Awesome what I have when it comes to the history of these parts...
