My KM rank insignia collection

[amiklic1]

Hello,

I have some KM rank insignia chevrons and I really like it, but I'm not sure if all of these is really KM.
Here are the pics, but I am not sure if all of these are really KM (I have some doubts about 8,9&10 - are they ww2 period ones and than 15-20, as I'm not really into KA items).

I'd like the help from more knowledgeabe colleagues to sort this out.

I don't see any problem with any of these. Curious 17 and 20 appear that they could be both Heer and KM.
I don't have enough experience but IMHO all look good.

17 and 20 are Heer to me for sure and some others maybe too depending if on the scan quality.
Nice collection overall !
