Strange collar tabs?

[NickG]

Found these while trolling the web...
Civilian but what is it? Some kind of postal, rail (ostbahn?) or Schuma tabs?
Any idea?

More views...strange braid too...Source claims it came with German insignia...

Not that it has anything to do with identifying these, but the braid is naval style.
