Thank you for your answers and your compliments

It is a great feeling that the questions that came to mind where pretty much the same for the both of us.
The part about this gun beeing used makes a lot of sence too, coincidentally i received my book on "kriegkunst zu Fuß" so i can read up on this subject.
The Schloss Dyck flintlock is very nice as well, looking forward to it.
I just read the part about the Kube auction again and i looked at the auction which sold that amazing Haquebut. I was shocked to see it had a estimate of €3500,-

and even more suprised that it DID NOT SELL at that auction !!!!
I will definitely apply for the membership, great knowledge is only one blink of an eye away when you take the efford to look at the right place.
