Unit marking question?

[NoncomRetired]

This marking: 3./K.7.47 could be either.........

3 Saxon Karabinier, Eskadron Regt, 7, waffen 47
or
3 Kurassier-Regt, Eskadron 7 waffen 47

I have found similiar markings in Jeff Noll's book but not exactly for this unit. (3)

(all periods are correct)

Thanks................
