Army (Heer) smoke troops 'Nebelwerfer' insignia set of an NCO officer candidate

Very nice tailor made set of Germnan army insignia, M36 pattern in dark green wool. Shoulder boards have maroon branch piping color for a member ofNebelwerfer-Abteilung 5 (mot), with the rank of Oberfeldwebel. The set of boards came together with a unique set of NCO officer candidate collar tabs, smaller than normal officer tabs, that have been periodicly addepted to Nebelwerfer by adding branch piping on the excisting tabs. This set came together and was recenly found in Germany.
