I agree Rudi.
1) It's the Tiger (P) which we don't see much of....and basically, having built one (my RammTiger), it's a SLICK kit.
2) Have you, or anyone else, seen a "testbed" build? Not to my knowledge. Show me a tank with it's test turret (like this), "weighted turret" (concrete rings for weight), or anything in that realm...I haven't seen one. Potential is quite large.
I will say though, the "oddity" of the coversion is both it's pro and con.
