But what does the "316" in the June 1939 batch run mean? As another example, my 1954 M-3 has a serial number of 704088. I take it that the "4,088" figure is the actual production number, but what does the "70" mean? Likewise for my 50mm Summicron with a number of 1234208. All those numbers must mean something.
