German WWII Badges (Identify)

[Ductex]

Hi All,
I'm a newbie, and do voluntary work at a local museum. from time to time we get various donations of German WWII artifacts.
I.ve now found a new interest in trying to identify these. Internet is great, however I do get stuck from time to time. Just wondered if you Guys could help me out ?
1 Armband Transportfuhrer 20cm x 10cm. ? Civilian / Trains ?
2 Cloth badge 13cm x 5cm ? German Labour front ?
3 Side cap 28cm x 11cm
Pics attached of these items.
I've managed to identify through various sites another 16 artifacts, but these have got me stumped.
Best regards Mike Heavens

The sidecap is a workcap [= Arbeitsmütze] of the National Air Defense League [= RLB/Reichsluftschutzbund].

The cogwheel-and-wreath device is a cap badge for the peaked caps worn by Stoßtrupp Leaders of the Werkscharen of the German Labor Front [= DAF/Deutsche Arbeitsfront].

The brassard identifies a "Transport Leader", i.e. the person in charge of a specific transport. Transportführer brassards were used by the Wehrmacht, but I cannot tell whether they were used by other services/organizations as well. (The term "Transportführer" as such is not exclusive to military terminology.)
