Norbert is the Director of Technical Operations or Service Manager for Krieghoff International in Pa. If you are a Krieghoff owner he's a guru for their guns.
It appears RK Shooting Family is RK Shooting Sports a Krieghoff dealer in Texas.
Norbert is a great guy and like I said if your a Krieghoff owner he's a great guy to know and work with. I had the pleasure of meeting him in their PA. center and he converted my double rifle to left hand for me.
