Here's the images of the slings for my 42 Inlands. The one on the left with the round buckle is from my 12/42. The one on the right is from the 8/42. The "2" is hard to see in the example on the right, but from every angle, it does appear to be a "2" in the date 1942. The right base lower right of that character (lower right of 2) is there. I know it's hard to see... Note the print font size varies between the two slings. But I suppose that's to be expected from production date to production date. And I suppose that ultimately, a definitive conclusion cannot be drawn from the one on the right. Of the 4 possible WW2 numbers, and having the lower right leg of the 2 still present, I figured it was a "2" as opposed to the other characters possible.
