Hi Gary, really interesting subject, and very detailed infos, I will wait for the next parts.
Rgeading your issue with the "overweathered" vehicles, I think it is just the question of approach. From the 100% replication of a vehicle, where every bolt is in position, to the artistic fantasies of Jean Bernard Andre, I think everything is acceptable, as far it is tell something about you and not just a repeat of a lesson. Those "madmaxed" Stug III-s and Tigers imho tell about the hopeless and sadness of war (yes you are right, in a bit surreal way), while the accurate reproduction tells about the desire of perfection, which is also an appreciated feature of a man.
Cheers,
Istvan
