Hello, Janos!
Thank you for your reply.
Why are you so sure of originality of my dagger?
I placed these photos on Russian military forum, and no one could answer me for certain whether it is original or fake. They say that most likely it is a fake, because they did not stamp a manufacturer's name on original daggers. But I am inclined to think that the lack of stamp on original daggers is a misguiding thinking, like with daggers 1932 model.
I know that this is a rare dagger, to my knowledge, about 50 pieces were made​​. Tell me, please, if there is any literature which describes in detail the dagger of Hungarian Air Force 1946 model year. I heard that there is a dagger in the Museum of Military History in Budapest, maybe someone has photos of the dagger from that museum.
Regards.
