Found this today on a French website, the guy modelled his as white 7 with a small yellow 7 on the rudder ?
My French is pretty poor but he used a few pics to show patches of cammo that matched up with a pic showing the seriel mumber on the tail of a Ta152 with some LW guys in front.

Yeah, there are other pics of this bird, at this point it was clearly White 7, but may have been yellow 7 at an earlier date.
