#1 is correct : 8.15x40R B Stahl Target (GSP5)
#2 appears to be the rare 10.25x42R Sd (MS15). Your example has the very early folded head construction “S” case which later became the “MS” solid base case (actually a 10.25x42R Kd). There was one of these in the Manfred Beutter collection auction which evidently came from the SFM Reference collection. Although very similar to the 10.5x42R MS cases this was positively identified by the Utendoerffer packet it came from.
thank you very much!
