Matthew,
Very good review of an interesting and unusual subject. Several things that you point out were rather disappointing to read (the overtly large positioning holes, the moulding lines, that lack of railing posts). It's a shame that recently Dragon appears to be taking many steps backwards when compared to many of their older releases. The really bright spots are their use of their highly detailed Panzer IV suspension and perhaps how this may make an impressively large sized representation of a rather unique vehicle.

Cheers,
Jan
