I was watching this also Jerry, but steered clear due to the consensus of opinion that a RAF KC badge never existed in A/A. I've not got it to hand, but from memory the loops your 2nd photo look like the ones on my 'new' badge that was discussed here -

Is the detail on the crown much poorer than the rest of the badge?
Got to say that the lugs on the recent ebay sale made me wonder.
