KG 26 lost hundred of aircraft during the war, so if you are interested in a precise time period or area, please say it.
The book "Torpedo los!" will have the full list of the crew losses, but no WNr (and no aircraft loss without casualty).
The following website will show (among other) KG 26 losses in and around Norway:

The following webpage will list the same losses and some more over North Sea and N Germany, but will have less details:

The last link only has 223 KG 26 aircraft destroyed or damaged beyond repair (and 112 damaged)....
