Does anyone have documentation or thoughts about the meaning of the following numbers found in boxes used by the Israeli armed forces? These are enclosed by a circle and the numbers in question are located at 6 o’clock. Usually, it is a 3-digit in the 100 or 700 range (Israeli made) or a 4-digit in the 4200 range (mostly foreign made; some Israeli made).
Numbers are found in boxes of cartridges of any caliber, including artillery. Also, the same number can be found in boxes of different calibers.
The other two numbers at 9 and 3 o’clock indicate month and year; the former may or may not match the lot number. The Hebrew character at 12 o’clock equals a Latin “N” (נ = Nun).
Any help would be appreciated.
