The GMC CCKW

Can someone post a picture of the early style CCKW gas cap,it's small like a civilian car,Joel probably has one.Thanks

Do you need one? I may have an extra NOS. GMC had a 2 1/4" and 2 1/2" OD Filler neck. I have never noticed the smaller, it may have been on the CCKWX.
Gotta be careful on small caps, as there are several that look right but only the Chev 4X4 and CCKW Part no are correct. some may not match the pattern on the neck. At the start of the War, many mv's had small caps, but they were usually specific to the make of truck. I like to do it by part number. There are at least 3 different WWII AC caps that all look similar but do not interchange.

I probably should have said this is for the CCKWX,right now I have a gas cap off one of my cushman trucksters on it, but I imagine there is a special cap that is correct.

What is the OD of the neck?

Here are a picture of a an early style gas cap from my cckw with 1574 cab and chassisnumber 32XXX. I have several early style gas caps, but they are as in pcture 2 and 3
