I'm not sure what relation Kurt was to Paul Jeager, but Deitrich Apel could tell you as Deitrich is Paul Jeagers nephew. Deitrich worked in Paul Jeagers shop in Jenkintown PA after coming to the US. That was at the time when Kurt Jeager ran a shop in Germany that supplied most of the engraving services to Paul's establishment in the US. Kurt's shop employed several engravers but the 'Kurt Jeager' name went on most every piece. Alot of post WW2 40's and 50's custom guns &engraving w/his name on it. Sporterized '03s, S&W Victorys, etc, along with then new US commercial sporting guns. I have been told but do not know for sure that Claus Willig(sp) was an engraver in Kurt Jeagers shop before coming to the US and working for Paul Jeager.
