Inland M1 Carbine Help

Any Idea what the green numbers in the stock mean?

Thanks

They are generally believed to be a sort of Julian dating system.
I am not exactly sure how they work on the carbines, but it may be the 104th day of 1943.
Someone else may jump in if I am wrong on the date. Very nice carbine and thanks for your service.

Thanks for the info Dave, that might be about right with the 4-43 marking on the barrel

Here is a better picture of my carbine all back together, except for the bolt as I am waiting for the bolt tool to reassemble it. https://www.milsurps.com/images/impo...DSC00959-1.jpg
