Chris, I didn't looked at the gold backside number, indeed even more suspicious!
i just had a look at the gold one and there are a few things i don't like:
-1 The way the letters are printed on the back, ok im talking about the gold one here but different than the bronze one!!!! It looks as if done in a hurry, sloppy.
-2 As you pointed out: the same number as the bronze one! Now with an age classification as posted above that's impossible for someone to have both! The award was at the wars end made, so no way someone could have both! Ok, it's still possible the gold is fake but the bronze is real, but what's the chance of CG finding both then at the same time and offer them for sale? I don't like it and wouldn't but such a rare award as the bronze one with this in mind, it just wouldn't feel okay...
-3 Look at the needle attachment, totally different! On top AND bottom!!!! (Though i like the bronze one more here, the idea of such big differences raises a doubt for the bronze too)
-4 The very bad way the SS is attached to it's surrounding borders, for such a high class award that looks very unproffesional? Also the bronze when looking at the backside picture shows on the right top S attachment a little sloppy soldering?
Maybe im seeing ghosts everywhere, but all together it's not very promising?
Unfortunately i don't have the books of Littlejohn, Mollo or Dodgkins, could anyone who has these scan them maybe? I'd love to see/read more, even it'it not very much....(The picture you posted is fromt he normal sports badges (drl?), no matter what year they are from, the dutch ss badges are from 1944 i think? (just from my head, don't have the source available so fast...), too bad the picture is not very high detailed nevertheless).
Also the videofragment, where is it from? I might be able to get my hands on it and would definately like to see it myself.EDIT: been reading too fast, i thought i read there was a videofragmetn of the dutch ss badge being handed out....
