When all else fails (one way or another), it's good to have a look at the good'ol Wikiperiferium:

It seems that none of the Ta-152 variants ever got to have much action. '46 stuff aside, this plane is one of the oddballs in the cast, just like the I-185, so you can't really expect it to be modeled as accurately as the rest of the German fighters in the game.
