[GTB]

Going through my Royal Arms badges in an effort to make some semblance out of what I have, it was obvious that I would stumble somewhere, even with the help of reference books.
Case in point, my attachment below.

Consists of a large cap size KC Royal Arms badge above 2 similar but smaller badges. The one on the left has a slider, so presumably a KC General Service beret badge? The one on the right, presumably a KC General Service collar badge (although it could just as well be something else)!

My question is: K&K only mention a smaller GS badge as being QC, so what can the small KC be?

Comments welcome, as always
