Hi Paul
Nice board.
Here are trades for the white career with a Lower career – unterer Dienst or einfacher Dienst or the Medium career – einfacher mittlerer Dienst or mittlerer Dienst. The latter is more likely the career level for your example.
Officials of the medium non technical career
Officials of the Lower career of the Food Supply Service and Garrison Admin
Intendatur of the medium career
Non technical Administration Service (Paymaster Branch)
Clothing depots after 1936
Food Supply officials of the lower career
Barracks Admin lower career
Shop Foreman: Bakery and Milling Service, Clothing Service, and Barracks service.
Hope this helps some
Larry
