I would like to get some information about this manufacturer. They come from Hamburg but I don't know anything about it apart from this. I'm also a new collector and would like to know: is it normal there is no metal attached to the piping? All the visor caps i've seen so far have this, this one doesn't.. So this one is very 'bendable'.. But when I look to the materials, I guess this is a good feurloschpolizei schirmmutze..
thanks for helping me
