Baumgarten:

Have seen the reference a time or two & collected a bit of ground truth, but it seems Kreiger & Gnädig were tube makers and used the trademark of a K enclosed by a G in the quadrilateral form. So anyone w/ a longarm w/ German tubes that has a brace of "Boxed Ks", come forward as I'd like to view them to see if indeed there are 2 concerns here: one being Kreiger & Gnädig w/ the K inside a G and another(Klett - K mechanic) that has just the "Boxed K".

Kreiger & Gnädig looks to have been active from WWI forward.

Seems the Motocycle wing was founded in 1919:

Must have been a short lived concern or there's additional info elsewhere seeing there were 4 brothers Krieger, Karl, Max, Peter & Oskar, all of Berlin, along w/ technical whiz Franz Gnädig. Gebrüder Krieger might just represent the trademark of K inside a G w/ an arrow thru it or it could represent the addition of Gnädig after WWI. Karl was the chauffeur of Kaiser Wilhelm II and a thrill seeker. All were pioneers in aviation up until WWI put a damper on that, so they turned to motorcycles. But Karl Krieger received a donated engine from Kaiser Wilhelm II, constructed his own plane & then was Nr. 113 in obtaining his pilot's license. He met his demise as a test pilot in the latter part of WWI.

So Gebrüder Krieger, being now Max, Peter & Oskar Krieger partner with designer Franz Gnädig in 1919 and transition from aviation to motorcycles. They were ahead of their time in design & Germany with is economic troubles, saw fierce competition in the motorcycle realm so the concern was absorbed in 1922. There were a couple more name changes & in 1927 when Paul Henkel Fahrradbau acquired the evolution of the original business and moved it to Mäbendorf near Suhl. Franz Gnädig left the partnership at this time & the whole of the ship sank in 1932 when Paul Henkel commited suicide in 1932. This was the motorcycle wing....
