Their will probably be very basic answers on very common cartridges here, but as i know nothing about 7.92 x 57 rounds, you’ll have to forgive me…
Of the two rounds pictured above;
The left (live / complete) round has a copper colour case and a similar colour bullet, both of which accepts a magnate.
I assume the case is copper washed steel with an (?SmK?) bullet?
The annulus seal is green with 3 stab crimps on the primer, as can be seen in the photo of the headstamp shown below…
Headstamp reads: P315 Xr1 2 40
The fired case on the right I am let to believe was recovered from a Messerschmitt Bf 109E-4 of I/JG53 (Brittany) which was shot down on Sept 15th 1940 over south Kent
Headstamp reads: P163 S* 10 38
The first of these rounds came from a bag of mixed surplus i aquired, the fired case i was given as a child mounted on a small plaque alongside a small piece of the aircraft fusilage.
I know most of the information regarding 7.92 x 57 is found on the carton labels, as demonstrated by recent threads on the forum, but can someone try to identify the type of rounds these are / were, for me please.
