Where could I find and buy hats like these?

Hube's hat looks more pointed at the tip than others? Its exactly the one I'd like..


Or the one Manstein is wearing?

Or any like Paulus is sporting?


Anyone know where I could find hats like these? Usually when I searhc, they are not pointed at the rim, or have wrinkles in the fabric. They are loose, not stiff like the ones in the pictures. Is there anywhere I can order one, possibly with size requests?
