JG11 got a batch of pre-productions, most if not all prototypes, in the very end of the war, in the same sort of last ditch effort that put all the Rechlin evaluation center's capable planes (262s, Ar234s, D9s, 152, etc) into action.
There were a few -C's in the field, but mostly H-0s and H-1s. The prototypes like JG11 got really were just a bootstrap sort of thing IMO.
Those 152-Cs probably saw action, but there's no record of it.
But as far as paint schemes are concerned, the only ones we could have in AH are most likely H-0's and prototype paint schemes in the case I described in the previous post.
