Who can identify this 30x86B Drill round? Is it British LV or German?
I also show a steel case German Practice shell 30x85B (213/30). Also a British 30x86B Exptl LV round that is stamped RA2/2957 on the case above the belt.
These all have a rim diameter of 31.9mm. Later 30mm LV had a 33.3mm rim.
Both the Drill round and German rounds have a small shoulder. The LV Exptl (in white) does not.
