This question is a little confusing.
There is no special information available on the label for who the cartridge was made for.
The first SmK and SmK tracers are known from 1928/1930. I don’t think they were made for the air force because after WW1 the allied did not allowed the Germans having any air planes.
The air force was starting to build up a fleet after they get the finances in the summer 1932.
In 1936 the PmK and the B-Patrone were introduced.
The Nitropenta powder used in the SmK-H cartridge was also used in the -v cartridge, made for the air force.
The Germans loaded PmK and B- Patronen with CWS steel cases for the air force. It was a disaster because sometimes a fired case stacked in the MG. Not a good thing if you are in an air battle.
From this time, only brass cases and cartridges with a primer 88 were made for the air force.
In 1943 the primer 43 was introduced, mainly to replace the primer 88 for the air force.
For practice shooting, the Luftwaffe used steel cases.
