The Panzer tracts 22-3 book wraps up the puzzle from an unususal story.
The roadwheels from the prototype series have the small holes near the rubber rim. The production version from the company "Kronprins" have not. The spoke wheels are the last stop gap in the production when the contracted company could not deliver.
The series of pictures on the testtrack that recently emerged show a production vehicle, with a roadwheel that has the little holes near the rubber rim
The Dresden surviver has both the "standard" and the spoke wheel and the open idler.
This nice picture taken by Mr. David Reay gives a good view on the wheels, but also shows the alternative idler. It also has the early production and prototype roadwheels.(The little holes near the rubber rim).
That means that all wheel questions are solved, and most amazing all the variants, even the most exotic, have survived.....
