Steuermann Kriegsmarine shoulder straps

[Dimas]

Here is shoulder boards I have

[grassy49]

Very nice shoulder boards

[lbsr]

What is the underlays color? On my screen it looks as feldgrau?

[wfrad]

It looks brown to me but the backs green.
The Field uniform should have dark green piping, which this may have been but age has deteriorated it. or I just have a crap computer.
To add to the problem, Marinebeamten Engineering Officials had silver insignia rather than gold with coloured piping:
Black for Technical.
Carmine Red for Legal.
Cornflower Blue for Administration and non technical.

[Dimas]

Really I have two sets and the color on the picture is near to the original

[wfrad]

Yes, nice set of straps.
