Confusing: The 7th ed of Leica Pocket Book has the E48 version as two different optical cells. One in use from 1957-1959, second from 1959-1979. The 1980 one is described as the "third version". A bit confusing as the heading uses the roman numeral "II".

In Puts' Lens compendium there are these relevant headings:
2.0/90 Summicron (I) from 1953 and 1957
2.0/90 Summicron (II), 1963
2.0/90 Summicron-M (III) 1980

The 1963 version is a Midland design so that works with the lens markings. Serial number could be on the barrel, frequently is on Canadian lenses.

Edit: I had a look at the catalogue, it certainly looks like the 1980 version.
