I don't think WNr 2579 was anything but a D-1 model, listed as such in all my sources.
The problem is with the report of the E-1. On a modern keyboard the letters D and E are very close together. If that was true for a German WW 2 typewriter, I don't know, but not impossible, meaning a typo writing E-1 instead of D-1 is within reason.

Of course it is perfectly possible the clerk made an error with the WNr itself but in this case it somehow feels logical there is a mistake between the D and E....

As usual thanks for the relevant details.

Cheers
