NAGr. 15 or not?

[DDT]

The book *Point Blank: October 1944* lists two losses as belonging to 1./NAGr. 15.
On 15 October 1944, Lt. Friedrich Drexel’s Fw 189 A-2 (V7 + 1A) was hit by Soviet flak and made a forced landing. According to the career database, Lt. Drexel belonged to 1.(H)/Aufkl.Gr. 32; the unit code V7 also belongs to this Staffel.
On 8 October 1944, the crew of Ogefr. Heinrich Fellner went missing in their Fw 189 A-2 (V7 + 1K). Based on the unit code, he also belonged to 1.(H)/Aufkl.Gr. 32.
I believe the RL records for this period are not yet available on the INVENIO website.
Does anyone have more information regarding which unit these crews belonged to?
Thanks in advance.
