None I have ever seen have an actual model number marked on the knives. My dad was black gang on a cruiser during WWII but he never mentioned whether he had bought it independently, issued or gifted.
There had been on Ebay a longer blade variant and I have seen a number of the seven inch blade examples with more bowie looking clips, so if you add up the two main versions, add these two just mentioned and the wood handled, that adds up to five. The mess kit ensemble almost certainly post war. I am forgetting where I saw a printed ad for sportsmans sales of the wood handle version. bBut then you have tooth and no tooth versions as well.
Be sure to search both EGW and Waterman knives on Ebay. There are currently several of both main patterns for sale
It is also possible that some of the multiple alloy spacer examples were one of those model #s but usually just three metal spacers or different leather washers, with others I have definitely modified that way.
In the end, I just don't know about the model #s and factory examples but the more bellied blade with no blade notch and those with just the angled (not a cap lift) notch appear the most often as relics of WWII.
