My girlfriend has recently come back from a trip to Ukraine. She knows I'm into history and specifically WW2. The markets in Eastern Europe are an amazing place to find many interesting things, such as this stamp. This is a picture exactly the same as the stamp that she brought back.
I'm aware it is a Luftwaffe stamp/seal, but I don't know exactly what it would have been used for? It is quite worn and has clearly been used a lot. Any help would be much appreciated .
This explains the meaning and use of the stamp. I would be very cautious about readily accepting the authenticity of a Nazi item, unless you have provenance, are capable of verifying it yourself, or have a credible third party do it. There is a thriving market in fake Nazi artifacts, as well as the means to make them, including rubber stamps.
Case in point, I was once offered a .25 caliber Mauser pistol that somebody had stamped with a Wehrmacht property mark, and was "used by the German post office" needless to say, I declined. Hopefully your stamp is legit!
