The bogie factory wraps it upAll that my octet of bogies was missing was a pair of pieces per component. The smaller and potentially less easily distinguishable was the bit that locked the bogie on the the axle. Then the second one, pretty clearly, was that cabin roof piece that was, I guessed, protecting the springs from pinecones falling from the trees or something like that.
After a pretty short glue-curing break I decided to install the whole set onto the lower hull at once. The first ones per side felt a bit flimsy, but as soon as all eight were on, the monster felt much more stable. I left it standing on its paws to get all the pieces to cure in a nicely straight and even position.
On the takeover laneAt this point the instructions were urging me to install the tracks, but as the roadwheelery was still curing, I didn't think it made any sense. So I jumped to the next implementable step, which happened to be the main turret's gun and its friends.
Hunting the pieces down took ages again, but at least these were much less cleanup-intensive than the previous bits. During my final session minutes I got some howitzer's read end pieces done and both turret seat setups. The ergonomy of said seats looked terrifying, but perhaps the crews weren't expected to survive long enough to develop any back issues.
