I've always been a student of Fokker and the LMG aircraft guns. I worked for a long time sorting out the meaning of the "L" of the LMG designation. The argument was always, luftgekühlt vs leichte, Machinen Gewehr (air cooled vs light, machine gun). I finally was able to "break the code" when a original parts manual for the aircraft gun surfaced in a military museum in Germany. The manual from the Spandau arsenal had the designation for the gun as lMG, the L in the lower case form, even though the gun is marked with the upper case form, LMG 08. With the aid of the curator when I pointed out the difference and that I thought is was a grammatical format possibility, he confirmed with the lower case usage it would be for luftgekühlt not Leichte.
Later in the war there were several "lightened" machine guns, and these also utilized the "LMG" designation, but with a capital "L" in print and on the gun. I believe the luftgekühlt terminology and usage had actually been superseded by the "Lightened" designation perhaps even before the end of the war and the term applied to both, as in any German manuals etc. I find on the aircraft gun they term it as a "L" or "Lightened" machine gun. I just had to go back to the origins to get the true story.
Recently, I found an ad page for Fokker for sale on ebay. I bought it. It is from the publication MOTOR and is from the Mai/Juni issue of 1918. Note the use of the term "LUFTWAFFEN". This surprised me as I had not heard of the term's usage until WW2 and in the form of "Luftwaffe".

Anyhow, my question to you is what do you think the term "LUFTWAFFEN" means here? I have some ideas, but I would like to hear from others.
Best wishes to all,
P.S. Check the other WW1 ads for sale by these chaps...very nice.
