Requesting some help with ZG Staffelkapitän
 

In researching a Bordfunker who flew exclusively with 2./Erp.Gr. 210, 2./SKG 210, 2./ZG1 and 2./ZG 26 I am attempting to ascertain all the Staffelkapitän of these respective units.

So far I have the following although there a few gaps which I would appreciate some help with, and of course I may well of made some mistakes also:

2./Erprobungsgruppe 210

Oberleutnant Wilhelm-Richard Roβiger 01-07-40 – 27-09-40 KIA
Oberleutnant Georg Knappe 00-09-40 – 24-04-40

2./SKG 210

Oberleutnant Friedrich Amende 24-04-41 - 29-07-41 KIA
Oberleutnant Fritz Andres 20-07-41 - 14-08-41 KIA
?

2./ZG 1

Oberleutnant August-Wilhelm Bier 04-01-1942 – 10-11-1942
Leutnant Oswald Reis 10-11-1942 – 18-12-1942
Hauptmann August-Wilhelm Bier 18-12-1942 – 10-10-1943

2./ZG 26

Oberleutnant Friedrich Sengschmitt 11-10-1943 – 11-01-1944 KIA
?

Any help whatsoever will be very well received in either adjusting or adding to the above.

Regards Richard.
