WH cyphers / auflagen post-war production ?

[Christophorus]

Good morning,

For your appreciation these three schoulderboard cyphers.
I am a little bit doubtful about them, i have the feeling there is a lack of details for the musician and verwaltung which appears new??
Moreover is the welding at the back normal?
I will greatly appreciate your precious help, i am somehow lost...

King regards

None of these strike me as being original war-time produced insignia, neither from the front nor the back sides. A hands-on inspection would be useful for evaluating them as to what types of metals were used to produce them and exactly how they are finished.

musicians postwar i think, HV is original but with new pins and re plated the snake original but has new pins

Snake possibly dates back to World War I or Weimar period. I also think HV is the original monogram.
