KM or SS armwinkel?

[lockheed nl]

Yesterday I got these two grounddug chevrons from a collectorfriend of my.
Are these two KM or SS? The backing seems black and the thread seems golden.
I hope you can help me.

Thanks.

Conventional KM pattern tresse. However, armed forces branches incorporated whatever material was available especially when the clock was approaching the 11th hour.
