Hello Rafngard,
agree with you that the first one is very recent, my guess would be around the 70s last century.
The second one I like very much and is from the 20s/30s in my opinion, the ferrule look like silver, to be sure you need to test it.
The third one is a typical piece from the 40s, the design of the okir engraving and the form let me think like this.
Nice small family!
Regards,
Detlef
