The top badge - I haven't seen reference to it in a book, but have seen one for sale as a shoulder strap badge although it appeared to be on a red collar patch, I don't know if the one I saw (online) was the same size as this one.
It was stated by the seller to be Dutch.
Link to the badge I saw for sale. The seller does mention that it may be a collar badge, doesn't know exactly what it is:
