Nice and informative review, Jacob!
Sounds to me like the D has indeed maybe drifted away a bit by leaving those previously-included parts out of this "premium" edition! And I was just about to plunk down some money to get one of these... Saved by the review bell, I guess.
Looks like it is indeed a cool kit, and the art-work is quite Volstad-stellar, but it doesn't seem to actually take things much beyond the earlier edition. And, at least right now, these things do not come cheap. Seeing as I have a couple of those, with the turned metal barrels, etc.... and the update kit along-side... I'll "make do" and do a bit of fiddling to get those wheels turned. It can be done. And adding those brake lines (and some suspension travel-limiter straps, too) is not too difficult. More challenging will be to make those hull-side access hatches open...

But I do have some plan for that!
Cheers!
Bob
