Do not know if this is relavant ... (besides it was S-1 140588 not 140580 SL+PV that was converted to Ju 88 P "Tank-buster")

I seem remember 3./KG 66 (Horch und Störstaffel) became 6.(F)/123 later, but I suspect designation "3/KG 66" having been a cover, possibly the real one was this here....

- Sonderkommando Rastádter/KG 40
An special SIGINT unit was attached in June 1943. Using the Do 217, He 111 and Ju 88 aircraft. Made operational tests in June, July and August 1943 to determine radar frequencies of the Allied Mk.III centimetric radar etc. Continiued operating untill April 1944, when it became a full electronic warfare unit (Horch und Störstaffel 2) finally absorbed by 4./FAGr 5 (Ju 290) in May 1944.

but I am no expert on these matters ...
