IBM 1401 ECO Cards

Robert Garner scanned some card forms (that were in the 1401 frame itself), below. He believes they could be a record of the 1401's "Engineering Change Orders" (ECO's), but not sure at all. They record events from Dec, 1963 to Dec, 1964.

Hallo!  Are these indeed a record of the 1401 CPU's ECO's?  If not, what?
Would you have an opportunity to translate the German?
Especially "Anderungsstand," which I couldn't find on any on-line 


- Robert
and we received the reply from Arnold and Rolf Schweinsberg
Aenderungsstand is "last level of alternation" at this time, 
   this is for a part number (Bauteilnummer).
This is not equal to any engineering change. 
   This seems not to be important for you.
Greetings from Arnold and Rolf
Ed questions - should "alternation" be "alteration"?? I am making that substitution (below, in italics) until corrected.
