Moin Blitz,
of course, there are also perfect reproductions of this winter hat, without a doubt.
The qualities are very different, often very inferior, and usually not worth the asking prices.
The "style" of the "Wintermütze" of that time is still common here in Germany.
Very gladly worn by German Neonazis, who keep "demonstrating" confused on the local streets.
There were probably no uniform standards for the Hitler Youth, after 1943/44 almost everything that was available was worn, if at all...
I would classify a very good reproduction today in a price range under 100,- Euros, including the badge from that time, of course, also as an imitation, nothing more.
If anything, then some originals are offered, they are not rarities, you can still see original caps at German flea markets for little money, usually without the insignia, of course, you have to ask for the "hardware".
Collecting greetings from Germany!
