You guys are right - it's a "K" rather than an "H". And Kölleda has a high degree of probability. But this does raise another question or two. There is no "Fliegergruppe Kölleda" listed in any of the reference works, and there were no flying units based at Kölleda until January 1945. As Norbert mentioned, it was strictly an aviation equipment office (Luftzeugamt) and an air park (Luftpark), and then from 1942 it was also a factory airfield (Industriehafen) for the ATG firm.

As far as I know, the term "Fliegergruppe" was always used in conjunction with a flying unit, and usually during the 1935-36 period only. So, could the abbreviation "Köll" be for a person rather than for an airfield? The use of the Umlaut greatly limits the possibilities. There are only a couple of names that might be candidates: KÖLLER, Max and KÖLLER, Otto. But both of these were Ergänzungs-Offiziere and neither had a flying license.

One other possibility: could "Fl.Gr." actually be "H.Gr." for Horstgruppe instead of Fliegergruppe? But then why would a Fliegerhorstkommandantur that had no aircraft have a flying suit?

Here is some basic information on Kölleda:

A branch rail line from Kölleda encircled the airfield serving the hangars at the N end and all the buildings at the S end.
