Thanks for all your help, Looks like I already found more history behind the armour than expected.
Next weekend when I have time again I need to try to get some order in all the information you all gave, so I can make a document for the future that it doesn't get lost after me.
I am confused at all the names and weird translation. I just found out that the names are the other way around in Japan: "Yamato Takada, Kikkawa family denrai", does this mean it has been made in order for Yamato Takada of the Kikkawa clan?
And the name changed into Yamato Joshigawa or do I misunderstand this?
The date of manufactoring in the auction says Senguko period, it is a huge timeframe, could the Gusoko (I just learned what that means) tell us more specific about the date?
And it looks to me that after the defeat in 1590, this Gusuko retired.
