Hello, such "gold" colored luft hangers do come in a wide vartion of colors. From almost faded, over a kind of brown, to a golden hue, to a more brighter goldbrown color. These are all the well known hangers which even have the RZM(!) mark on the reverse of the top fitting. These are all for sure no general´s hangers but imho should simply fit the brown leather parts (eg belt) of the common luft uniform.
I think that only hangers with a real deep and bright true gold color can be assumed to be general´s hangers and they for sure should pass the acetone test. Sorry I cannot show you a specimen because during all of my time of collecting until now I never came over a -for me- doubtless certain hanger which has been offered to me.
Regards,
